msm: kgsl: Set requested power state to NONE after resume

When GPU resumes from suspend requested state is not cleared to NONE.
Due to this idle reporting is not done and GPU stays at MAX freq. As
a fix if the current power state is already ACTIVE and request is
made for active power state then clear the requested state immediately.

lib: genalloc: Change chunk allocation to vmalloc

Change the chunk allocation from kmalloc to vmalloc for
allocations greater than a page. This allows large
chunks to be allocated from physically non-contiguous
memory and increases the chance of the allocation
succeeding.
