tipc: remove pointless name sanity check and tipc_alphabet array
There is no real reason to check whether all letters in the given media name and network interface name are within the character set defined in tipc_alphabet array. Even if we eliminate the checking, the rest of checking conditions in tipc_enable_bearer() can ensure we do not enable an invalid or illegal bearer.
