mesa: fix proxy texture error handling in glTexStorage()

Browse source 
This is basically a follow-on to 1f5b1f9846.
Basically, generate GL errors for ordinary invalid parameters for proxy
targets the same as for non-proxy targets.  Only texture size and OOM
errors should be handled specially for proxies.

Note: This is a candidate for the stable branches.
