Subject: [PATCH] bluetooth: remove useless variable in virtual hci driver

Commit ac28494c has removed the option to give a minor number as
parameter for VHCI driver. Remove the variable used for that parameter.
Print the error code when registering the device fails, instead of the
requested minor number (which would always be MISC_DYNAMIC_MINOR).
