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.
