xfs: drop ASSERT(0) on unrecognized log item type

The item type passed to ITEM_TYPE() comes from the on-disk log, so a
fuzzed or crafted image can reach the "unrecognized type" path in
xlog_recover_reorder_trans() and trip its ASSERT(0) on a
CONFIG_XFS_DEBUG kernel.  The -EFSCORRUPTED return handles it fine; drop
the assert.
