Convert atomic_inc(&bh->b_count) to get_bh(bh) for consistency.

'buffer_head' should be 'journal_head'.

Fail journal creation if __getblk() returns NULL.  unlikely() is
added because it is called in a loop and we've been OK without
the check until now.

Convert set/clear_bit(BH_JWrite, ...) to set/clear_buffer_jwrite()

This fixes a WARN backtrace in mark_buffer_dirty() that occurs during unmount
when the underlying block device is removed.  This bug has been seen on System
Z when removing all paths from a multipath-backed ext3 mount; on System P when
injecting enough PCI EEH errors to make the SCSI controller go offline; and
similar warnings have been seen (and patched) with ext2/ext4.

The super block update from a previous operation has marked the buffer as in
error, and the flag has to be cleared before doing the update. Similar changes
have been made to ext4 by commit 914258bf2cb22bf4336a1b1d90c551b4b11ca5aa.

Remove goto statement which jumps to very next line. Also remove
target label because it is no longer used anywhere.
