gfs2: Add proper lockspace locking

Browse source

[ Upstream commit 6ab26555c9 ]

GFS2 has been calling functions like dlm_lock() even after the lockspace
that these functions operate on has been released with
dlm_release_lockspace().  It has always assumed that those functions
would return -EINVAL in that case, but that was never guaranteed, and it
certainly is no longer the case since commit 4db41bf4f0 ("dlm: remove
ls_local_handle from struct dlm_ls").

To fix that, add proper lockspace locking.
