not handle errors from gettimeofday".

Fix by retrying gettimeofday() several times if it fails in ut_usectime().
If it fails on all calls then return error to the caller to be handled
at higher level.

Update the variable innodb_row_lock_time_max in SHOW STATUS output only
if ut_usectime() was successful.
