iopoll: fix function parameter names in read_poll_timeout_atomic()

[ Upstream commit 878004e ]

Correct the function parameter names to avoid kernel-doc warnings
and to emphasize this function is atomic (non-sleeping).

Warning: include/linux/iopoll.h:169 function parameter 'sleep_us' not
 described in 'read_poll_timeout_atomic'
Warning: ../include/linux/iopoll.h:169 function parameter
 'sleep_before_read' not described in 'read_poll_timeout_atomic'

Fixes: 9df8043 ("iopoll: Generalize read_poll_timeout() into poll_timeout_us()")
