[PATCH 25/30] zram: Add missing annotatin for zram_slot_lock()

[Jules Irenge]

Sparse reports a warning at zram_slot_lock()
warning: context imbalance in zram_slot_lock() - wrong count at exit
The root cause is the missing annotation at zram_slot_lock()
Add the missing  __acquires(ZRAM_LOCK) annotation
