kfifo: fix warn_unused_result
Fix the "ignoring return value of '...', declared with attribute
warn_unused_result" compiler warning in several users of the new kfifo
API.
It removes the __must_check attribute from kfifo_in() and
kfifo_in_locked() which must not necessary performed.
Fix the allocation bug in the nozomi driver file, by moving out the
kfifo_alloc from the interrupt handler into the probe function.
Fix the kfifo_out() and kfifo_out_locked() users to handle a unexpected
end of fifo.
