xfs: refactor the buffer cancellation table helpers
Replace the somewhat convoluted use of xlog_peek_buffer_cancelled and
xlog_check_buffer_cancelled with two obvious helpers:
xlog_is_buffer_cancelled, which returns true if there is a buffer in
the cancellation table, and
xlog_put_buffer_cancelled, which also decrements the reference count
of the buffer cancellation table.
Both share a little helper to look up the entry.
