tcp: fix tcp_min_tso_segs sysctl

Browse Source 
commit d24f511b04b8b159b705ec32a3b8782667d1b06a upstream.

tcp_min_tso_segs is now stored in u8, so max value is 255.

255 limit is enforced by proc_dou8vec_minmax().

We can therefore remove the gso_max_segs variable.

Fixes: 47996b489bdc ("tcp: convert elligible sysctls to u8")
