[PATCH 3/5] xfs: remove unused xfs_buf_iodone declaration

[Zizhi Wo]

From: Zizhi Wo <wozizhi@xxxxxxxxxx>

Commit 664ffb8a429a ("xfs: move the buffer retry logic to xfs_buf.c")
removed the xfs_buf_iodone() implementation and its last caller in
favour of xfs_buf_ioend_finish(), but the declaration in xfs_buf_item.h was
left behind. It has been a dead prototype ever since (2020).

Remove the stale declaration.
