msm: kgsl: use kvcalloc for ringbuffer submission

Browse Source 
kcalloc returns out of memory in low memory conditions even if memory
is available in non-contiguous manner. This results in failure to
submit commands to ringbuffer. Use kvcalloc in place of kcalloc so
that when kcalloc fails in low memory conditions, commands can be
submitted if kvcalloc can provide enough memory.
