blockdev: Fix drive_del not to crash when drive is not in use

Watch this:

(qemu) drive_add 0 if=none,file=tmp.img
    OK
    (qemu) info block
    none0: type=hd removable=0 file=tmp.img ro=0 drv=raw encrypted=0
    (qemu) drive_del none0
    Segmentation fault (core dumped)

do_drive_del()'s code to clean up the pointer from a qdev using the
drive back to the drive needs to check whether such a device exists.
