LU-14069 ldlm: Fix unbounded OBD_FAIL_LDLM_CANCEL_BL_CB_RACE wait

in ldlm_handle_cp_callback the while loop is clearly supposed
to be limited by the "to" value of 1 second, but is not.
Seems to have been broken by all the Solaris porting in HEAD
all the way back in 2008.
Restore the to assignment to make it not hang indefinitely.
