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.
