svga: Always set the alpha value to 1 when sampling using an XRGB view

If the XRGB view is sampling from an ARGB svga format, change
PIPE_SWIZZLE_W to PIPE_SWIZZLE_1 for all channels.
Previously we unconditionally set PIPE_SWIZZLE_1 on the alpha channel which
could be both insufficient and incorrect.
