[PATCH 4.15 120/128] mmc: mmc_test: Ensure command queue is disabled for testing

[Greg Kroah-Hartman]

4.15-stable review patch.  If anyone has any objections, please let me know.

[ 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")
