The original condition incorrectly used &h->chunk instead of
h->chunk in the calculation whether the object is in the chunk. This
could lead to the wrong behavior as the first branch gave incorrect
result and thus sometimes the entire obstack was freed even though
object was not NULL.
The commit also simplifies the logic, we can use pointer arithmetic
here and just do h->chunk + 1 as it gives the same result as
(FAR char *)h->chunk + sizeof(struct _obstack_chunk). This saves
unnecessary cast and sizeof.
The second branch should be less than or equal, not just less than.
This ensures the object is correctly located in the chunk even after
previous obstack_finish was called.

When using the serial framework buffer, if the buffer is full, excess
data is cached in the usb req buffer. The CDCACM driver doesn't know
when the upper layer will read data from the serial buffer, so it
needs to periodically check if the cached data can be put into the
serial buffer. However, when using zero-copy, each usb req buffer
needs to be completely read before actively switching to the next
req buffer, so the timer is not needed to assist to query.

in cdcacm_sndpacket, If `if (priv->wrcontainer)` is true, then
`priv->wrcontainer` is set to NULL. If an interrupt occurs before
`priv->wrcontainer` is reassigned after being NULL,
`priv->wrcontainer` will be reassigned once during the interrupt,
and `nwrq--` will be called, but no data will be sent at this time.
Only when data is sent by calling `txint` will `priv->wrcontainer`
be reassigned and `nwrq--` called again. This causes the issue.

When CONFIG_CDCACM_DISABLE_TXBUF is enabled, if the USB is
unplugged during serial data transmission, it is possible
that cdcacm will enter the unbind process, and reqbuf will
be released, causing a crash during serial write.
