acpi_os_vprintf: Use printk_get_level() to avoid unnecessary KERN_CONT
acpi_os_vprintf currently always uses a KERN_CONT prefix which may be followed immediately by a proper KERN_<LEVEL>. Check if the buffer already has a KERN_<LEVEL> at the start of the buffer and avoid the unnecessary KERN_CONT. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Rafael J.
