i965: Fail to blit rather than assert on invalid pitch requirements.
Dungeon Defenders hits TexImage()'s try_pbo_upload() path where
image->Width == 2, which doesn't meet intelEmitCopyBlit's requirement
that the pitch needs to be a multiple of 4.
Since intelEmitCopyBlit can already fail for a myriad of other reasons,
and it's not clear that other callers are immune to this failure mode,
simply make it return false rather than assert.
Fixes Dungeon Defenders on i965/Ivybridge. Now playable (aside from
having to work around the EXT_bindable_uniform issue).
NOTE: This is probably a candidate for the 9.0 branch.
