msm: mdss: Increase fbmem buf ref count before use
The reference count for fbmem buf is not increased before use,
which means it can be get freed unintentionally when the reference
count is decreased to "0". In this case, there is possibility of
use after free. Ensure that fbmem buf refcount is incremented
before use.
