Hey all -

While developing my io-error patches (posted previously), I skipped the
resize stuff, opting to come back to it later, since it involved
re-ordering operations so we don't blow ourselves out of the water.
Today, I started digging into that code, and found that if -oresize is
used when the filesystem is read-only, it will attempt to start a
transaction on a read-only filesystem. When CONFIG_REISERFS_CHECK is
enabled, this causes an assertion failure.

mount -r /dev/hda8 /mnt
mount -oremount,resize=123456 /mnt
*panic*

The attached patch fixes the problem. It also moves the reiserfs_resize
call after the filesystem is made read-write on remount. This is so the
following succeeds:

mount -oremount,resize=123456,rw /mnt
