Revert "epoll: use freezable blocking call"
This reverts commitwifi-calibration1c441e9212
(epoll: use freezable blocking call) which is reported to cause user space memory corruption to happen after suspend to RAM. Since it appears to be extremely difficult to root cause this problem, it is best to revert the offending commit and try to address the original issue in a better way later.
