gfs2: Get rid of sd_reserving_log
This counter and the associated wait queue are only used so that
gfs2_make_fs_ro can efficiently wait for all pending log space
allocations to fail after setting the filesystem to read-only. This
comes at the cost of waking up that wait queue very frequently.
Instead, when gfs2_log_reserve fails because the filesystem has become
read-only, Wake up sd_log_waitq. In gfs2_make_fs_ro, set the file
system read-only and then wait until all the log space has been
released. Give up and report the problem after a while. With that,
sd_reserving_log and sd_reserving_log_wait can be removed.
