ALLOC_MEM_FLAGS_* used are the same as the KFD_IOC_ALLOC_MEM_FLAGS_*,
but they are interweavedly used in kernel driver, resulting in bad
readability. For example, KFD_IOC_ALLOC_MEM_FLAGS_COHERENT is totally
not referenced in kernel, and it functions in the kernel through
ALLOC_MEM_FLAGS_COHERENT, causing unnecessary confusion.
Replace all occurrences of ALLOC_MEM_FLAGS_* by
KFD_IOC_ALLOC_MEM_FLAGS_* to solve the problem.
