[PATCH AUTOSEL 6.18-6.6] gfs2: fix remote evict for read-only filesystems

From: Andreas Gruenbacher <[email protected]>

[ Upstream commit 64c10ed9274bc46416f502afea48b4ae11279669 ]

When a node tries to delete an inode, it first requests exclusive access
to the iopen glock.  This triggers demote requests on all remote nodes
currently holding the iopen glock.  To satisfy those requests, the
remote nodes evict the inode in question, or they poke the corresponding
inode glock to signal that the inode is still in active use.

This behavior doesn't depend on whether or not a filesystem is
read-only, so remove the incorrect read-only check.
