drm/qxl: Complete exception handling in qxl_device_init()
A coccicheck run provided information like the following.
drivers/gpu/drm/qxl/qxl_kms.c:295:1-7: ERROR: missing iounmap;
ioremap on line 178 and execution via conditional on line 185
Generated by: scripts/coccinelle/free/iounmap.cocci
A jump target was specified in an if branch. The corresponding function
call did not release the desired system resource then.
Thus use the label “rom_unmap” instead to fix the exception handling
for this function implementation.
