mesa/main: Fix multisample texture initialize

Browse Source 
Sampler of Multisample textures wasn't initialized correct. So when
texture object created as  multisample its sampler is initialized in a
individual case. We change the initial state of TEXTURE_MIN_FILTER and
TEXTURE_MAG_FILTER to NEAREST.
These changes are approved by KhronosGroup.
