Fix uninitialized use of local variable pitch in radeon_setup_kernel_mem
Fixes server reset.
Pointed out by clang:
../../src/radeon_kms.c:2721:9: warning: variable 'pitch' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized]
if (!info->front_buffer) {
^~~~~~~~~~~~~~~~~~~
../../src/radeon_kms.c:2765:27: note: uninitialized use occurs here
pScrn->displayWidth = pitch / cpp;
^~~~~
