Darrick J. Wong 4bb73d0147 xfs: check sb_agblocks and sb_agblklog when validating superblock
Currently, we don't check sb_agblocks or sb_agblklog when we validate
the superblock, which means that we can fuzz garbage values into those
values and the mount succeeds.  This leads to all sorts of UBSAN
warnings in xfs/350 since we can then coerce other parts of xfs into
shifting by ridiculously large values.

Once we've validated agblocks, make sure the agcount makes sense.
