[ Upstream commit a1e627af32ed60713941cbfc8075d44cad07f6dd ]
If the "test->highmem = alloc_pages()" allocation fails then calling
__free_pages(test->highmem) will result in a NULL dereference. Also
change the error code to -ENOMEM instead of returning success.
Fixes: 2661081f5ab9 ("mmc_test: highmem tests")
