[PATCH 4/5] xfs: wait for I/O completion when writing out pages in xfs_setattr_size

[Christoph Hellwig <hch@xxxxxxxxxxxxx>]

The current code relies on the xfs_ioend_wait call later on to make sure
all I/O actually has completed.  The xfs_ioend_wait call will go away soon,
so prepare for that by using the waiting filemap function.
