qemu_conf: Fix double free problem for cfg->firmwares

cfg->firmwares still points to the original memory address after being
freed by virFirmwareFreeList(). As cfg get freed, it will be freed again
even if cfg->nfirmwares=0 which eventually lead to crash.

The patch fix it by setting cfg->firmwares to NULL explicitly after
virFirmwareFreeList() returns
