[TIPC]: Force linearization of non-linear sk_buffs
This patch allows TIPC to process incoming messages that are stored in a fragmented sk_buff, by forcing the linearization of any such messages it receives. Note: This is an interim solution to allow TIPC to operate with Ethernet devices that generate non-linear buffers (such as the gianfar driver), until such time as the rest of TIPC is enhanced to handle sk_buffs with multiple data areas.
