[ Upstream commit 59546e8744 ]

Fix

ksft.h: In function ‘ksft_ready’:
ksft.h:27:9: warning: ignoring return value of ‘write’ declared with attribute ‘warn_unused_result’

ksft.h: In function ‘ksft_wait’:
ksft.h:51:9: warning: ignoring return value of ‘read’ declared with attribute ‘warn_unused_result’

by checking the return value of the affected functions and displaying
an error message if an error is seen.
