block: Fix -drive for certain non-string scalars

The previous commit fixed -blockdev breakage due to misuse of the
qobject input visitor's keyval flavor in bdrv_file_open().  The commit
message explain why using the plain flavor would be just as wrong; it
would break -drive.  Turns out we break it in three places:
nbd_open(), sd_open() and ssh_file_open().  They are even marked
FIXME.  Example breakage:

    $ qemu-system-x86 -drive node-name=n1,driver=nbd,server.type=inet,server.host=localhost,server.port=1234,server.numeric=off
    qemu-system-x86: -drive node-name=n1,driver=nbd,server.type=inet,server.host=localhost,server.port=1234,server.numeric=off: Invalid parameter type for 'numeric', expected: boolean

Fix it the same way: replace qdict_crumple() by
qdict_crumple_for_keyval_qiv(), and switch from plain to the keyval
flavor.
