Alexey Izbyshev cbe7b911e0 io_uring: Fix io_cqring_wait() not restoring sigmask on get_timespec64() failure ...

Commit 978e5c19df upstream.

This bug was introduced in commit 950e79dd73 ("io_uring: minor
io_cqring_wait() optimization"), which was made in preparation for
adc8682ec6 ("io_uring: Add support for napi_busy_poll"). The latter
got reverted in cb31821673 ("Revert "io_uring: Add support for
napi_busy_poll""), so simply undo the former as well.
