tipc: remove pointless name sanity check and tipc_alphabet array

Browse source 
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.
