Gregory Nutt 9ff1795760 Check return from nxsem_wait_initialize() ...

Resolution of Issue 619 will require multiple steps, this part of the first step in that resolution:  Every call to nxsem_wait_uninterruptible() must handle the return value from nxsem_wait_uninterruptible properly.  This commit is only for rwbuffer.c and those files under drivers/serial, drivers/timers, and drivers/usbdev.

This commit completes that step for all of the files under drivers/.  Still remaining:  All of the files under arch/.
