Yang ChungFan 4db8c826d7 drivers/pipes: Use inode reference counter instead of device reference counter to handle dup(). I found that if I dup() a pipe, the reference counter d_refs is not increased. If I close any of the fd, backed by the same pipe, the pipe will be freed. This causes any further usage on the fd referencing a non existent pipe. This change uses the inode reference counter, which is properly maintained during dup().

CONFIG_NFILE_DESCRIPTORS=0 can no longer be used to disable the file system. NuttX with no file system does not make sense.
