[PATCH 5.4 066/177] fs/nfs: Use fatal_signal_pending instead of signal_pending

[Greg Kroah-Hartman]

From: zhouchuangao <zhouchuangao@xxxxxxxx>

commit bb002388901151fe35b6697ab116f6ed0721a9ed upstream.

We set the state of the current process to TASK_KILLABLE via
prepare_to_wait(). Should we use fatal_signal_pending() to detect
the signal here?

Fixes: b4868b44c562 ("NFSv4: Wait for stateid updates after CLOSE/OPEN_DOWNGRADE")
