mtd: maps: vmu-flash: Fix the (mtd core) switch to ref counters
commit a7d84a2e7663bbe12394cc771107e04668ea313a upstream.
While switching to ref counters for track mtd devices use, the vmu-flash
driver was forgotten. The reason for reading the ref counter seems
debatable, but let's just fix the build for now.
Fixes: 19bfa9ebebb5 ("mtd: use refcount to prevent corruption")
