mesa: fix MSVC bitshift overflow warnings
In the BITFIELD_MASK() macro, if b==32 the expression evaluates to ~0u, but the compiler still sees the expression (1 << 32) in the unused part and issues a warning about integer bitshift overflow. Fix that by using (b) % 32 to ensure the max shift is 31 bits. This issue has been present for a while, but shows up much more often because of the recent VBO changes.
