drivers/base/memory.c: fix kw reported issue

Fix KW reported 'NULL pointer dereference' issue. This is fixed in the
upstream as part of 848e19ad3c335 ("drivers/base/memory.c: drop the
mem_sysfs_mutex") but the reason not to pick this up as it is that it
contains the additional changes not so important for 4.19 kernels.
