virtio_blk: add default case to cmd type switch
On compilation, gcc correctly detects that we do not handle all types: In function ‘blk_done’: warning: enumeration value ‘REQ_TYPE_FS’ not handled in switch warning: enumeration value ‘REQ_TYPE_SENSE’ not handled in switch warning: enumeration value ‘REQ_TYPE_PM_SUSPEND’ not handled in switch warning: enumeration value ‘REQ_TYPE_PM_RESUME’ not handled in switch warning: enumeration value ‘REQ_TYPE_PM_SHUTDOWN’ not handled in switch warning: enumeration value ‘REQ_TYPE_LINUX_BLOCK’ not handled in switch warning: enumeration value ‘REQ_TYPE_ATA_TASKFILE’ not handled in switch warning: enumeration value ‘REQ_TYPE_ATA_PC’ not handled in switch which is a bit pointless since this is at the end of the request processessing. Add a default case that just breaks out. Signed-off-by: Jens Axboe <jaxboe@fusionio.com>
