[PATCH 5.10 002/171] gfs2: Check for active reservation in gfs2_release

[Greg Kroah-Hartman]

From: Andreas Gruenbacher <agruenba@xxxxxxxxxx>

[ Upstream commit 0ec9b9ea4f83303bfd8f052a3d8b2bd179b002e1 ]

In gfs2_release, check if the inode has an active reservation to avoid
unnecessary lock taking.
