nv30: Disable msaa unless requested from the env by NV30_MAX_MSAA
Some modern apps try to use msaa without keeping in mind the restrictions on videomem of older cards. Resulting in dmesg saying: [ 1197.850642] nouveau E[soffice.bin[3785]] fail ttm_validate [ 1197.850648] nouveau E[soffice.bin[3785]] validating bo list [ 1197.850654] nouveau E[soffice.bin[3785]] validate: -12 Because we are running out of video memory, after which the program using the msaa visual freezes, and eventually the entire system freezes. To work around this we do not allow msaa visauls by default and allow the user to override this via NV30_MAX_MSAA.
