Revert "tipc: check the bearer min mtu properly when setting it by netlink"

Browse Source 
This reverts commit 2937127d24 which is
commit 35a089b5d793d2bfd2cc7cfa6104545184de2ce7 upstream.

It breaks the Android kernel ABI and is not needed for Android devices,
so it is safe to revert for now.  If it is determined that it is needed
in the future, it can be brought back in an abi-preserving way.
