gfs2: Faster gfs2_upgrade_iopen_glock wakeups
Move function needs_demote() to glock.h and rename it to
glock_needs_demote(). In handle_callback(), wake up the glock when
setting the GLF_PENDING_DEMOTE flag as well. (Setting the GLF_DEMOTE
flag already triggered a wake-up.)
With that, check for glock_needs_demote() in gfs2_upgrade_iopen_glock()
to wake up when either of those flags is set for the inode glock: the
faster we can react to contention, the better.
The GLF_PENDING_DEMOTE flag is only used for inode glocks (see
gfs2_glock_cb()) so it's okay to only check for the GLF_DEMOTE flag in
gfs2_drop_inode(). Still, using glock_needs_demote() there as well
makes the code a little easier to read.
