[IA64] perfmon: Change vmalloc to vzalloc and drop memset.
vzalloc() nicely zeroes memory for us, so we don't have to do a vmalloc() and then manually memset() the returned memory when all we want is for it to be zero. Patch changes this for pfm_rvmalloc(). Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: Tony Luck <tony.luck@intel.com>
