xfs: remove duplicate INO1_WRITTEN check

Browse Source 
Commit a23eca8844 ("xfs: fix exchange-range reflink flag clearing
issue with INO1_WRITTEN") duplicated commit b2d5a81dae ("xfs: fix
exchange-range reflink flag clearing issue with INO1_WRITTEN"), so
xmi_can_exchange_reflink_flags() ended up with two identical
XFS_EXCHMAPS_INO1_WRITTEN checks.  The second one is dead code,
since the first one already returned false.  Remove it.
