xfs: restore bi_bdev in xfs_zone_gc_write_chunk

xfs_zone_gc_write_chunk relies on bi_bdev to still be valid, which is not
true when XFS is used on top of a stacked block device.  This can lead to
misdirected GC writes, writing of plain text when using dm-crypt, or
miscalculated I/O limits in xfs_zone_gc_split_write.

Fix this by reassigning bi_bdev.
