[GIT PULL] iomap: small cleanups for 5.5

["Darrick J. Wong" <djwong@kernel.org>]

Hi Linus,

Please pull this series containing some more new iomap code for 5.5.
There's not much this time -- just removing some local variables that
don't need to exist in the iomap directio code.

The branch merges cleanly against this morning's HEAD and survived a few
days' worth of xfstests.  The merge was completely straightforward, so
please let me know if you run into anything weird(er than my dorky tag
message).
