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

[Thadeu Lima de Souza Cascardo]

Commit ac28494c has removed the option to give a minor number as
parameter for VHCI driver. Remove the variable used for that parameter.
Printing the requested minor number, which would always be
MISC_DYNAMIC_MINOR, is not needed. And return the error code returned by
misc_register, instead of -EIO in init function.
