block: Make bdrv_create_file() ':' handling consistent 

Filenames may start with "<protocol>:" to explicitly use a protocol like
nbd.  Filenames with unknown protocols are rejected in most of QEMU
except for bdrv_create_file().  Even if a file with an invalid filename
can be created, QEMU cannot use it since all the other relevant
functions reject such paths.  Make bdrv_create_file() consistent.
