mesa: clear existing swizzle info before bitwise-OR
This patch fixes a bug in big-endian treatment, where the previous
swizzle info wasn't cleared before a new swizzle info was inserted into
the format field using a bitwise-OR operation.
v2: use MESA_ARRAY_FORMAT_SWIZZLE_*_MASK instead of numeric constants
v3: align according to coding style
