[PATCH 5.16 079/203] Revert "gfs2: check context in gfs2_glock_put"

From: Greg Kroah-Hartman

From: Andreas Gruenbacher <agruenba@xxxxxxxxxx>

commit 356b8103d4c495d5440e3e687db9026ec2b76043 upstream.

It turns out that the might_sleep() call that commit 660a6126f8c3 adds
is triggering occasional data corruption in testing. We're not sure
about the root cause yet, but since this commit was added as a debugging
aid only, revert it for now.

This reverts commit 660a6126f8c3208f6df8d552039cda078a8426d1.

Fixes: 660a6126f8c3 ("gfs2: check context in gfs2_glock_put")
