[NET]: Fix socket bitop damage
The socket flag cleanups that went into 2.6.12-rc1 are basically oring the flags of an old socket into the socket just being created. Unfortunately that one was just initialized by sock_init_data(), so already has SOCK_ZAPPED set. As the result zapped sockets are created and all incoming connection will fail due to this bug which again was carefully replicated to at least AX.25, NET/ROM or ROSE. In order to keep the abstraction alive I've introduced sock_copy_flags() to copy the socket flags from one sockets to another and used that instead of the bitwise copy thing. Anyway, the idea here has probably been to copy all flags, so sock_copy_flags() should be the right thing. With this the ham radio protocols are usable again, so I hope this will make it into 2.6.13.
