i965: Do not set bilinear_filter flag in case of multisample blits
Setting bilinear_filter flag in case of multisample blits with
GL_LINEAR filter causes incorrect behavior in translate_dst_to_src()
function. This broke Modern Warfare (1, 2 and 3) on SNB, IVB and HSW.
Tested on SNB and IVB, no Piglit regressions. Trace file of the game
(taken with apitrace) works fine with this patch.
