Correct the parameter names to avoid kernel-doc warnings:

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: 9df8043a546d ("iopoll: Generalize read_poll_timeout() into poll_timeout_us()")
