Subject: [PATCH] mmc: mmc_test: Ensure command queue is disabled for testing
Git-commit: 23a185254ace8e63dc4ca36e0315aed9440ae749
Patch-mainline: v4.16-rc1
References: bsc#1051510

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.
