drm/amdkfd: Fix gfx8 MEM_VIOL exception handler
When MEM_VIOL is asserted the context save handler rewinds the
program counter. This is incorrect for any source of the exception.
MEM_VIOL may be raised in normal operation by out-of-bounds access
to LDS or GDS and does not require special handling.
Remove PC adjustment when MEM_VIOL has been raised.
