Alexey Izbyshev 9bb4c5655a io_uring: Fix io_cqring_wait() not restoring sigmask on get_timespec64() failure ...

Commit 978e5c19dfefc271e5550efba92fcef0d3f62864 upstream.

This bug was introduced in commit 950e79dd7313 ("io_uring: minor
io_cqring_wait() optimization"), which was made in preparation for
adc8682ec690 ("io_uring: Add support for napi_busy_poll"). The latter
got reverted in cb3182167325 ("Revert "io_uring: Add support for
napi_busy_poll""), so simply undo the former as well.
