4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Adrian Hunter <adrian.hunter@xxxxxxxxx>
[ Upstream commit 23a185254ace8e63dc4ca36e0315aed9440ae749 ]
mmc_test disables the command queue because none of the tests use the
command queue. However the Reset Test will re-enable it, so disable it in
that case too.
Fixes: 9d4579a85c84 ("mmc: mmc_test: Disable Command Queue while mmc_test is used")
