Subject: hw/display/qxl: Have qxl_log_command Return early if no log_cmd
 handler
MIME-Version: 1.0

Git-commit: 61c34fc194b776ecadc39fb26b061331107e5599
References: bsc#1205808

Only 3 command types are logged: no need to call qxl_phys2virt()
for the other types. Using different cases will help to pass
different structure sizes to qxl_phys2virt() in a pair of commits.
