intel: Fix emit_linear_blit to use DWORD aligned width blits

The width of the 2D blits used to copy the data is defined as a 16-bit
signed integer, but the pitch must be DWORD aligned. Limit to an integral
number of DWORDs, (1 << 15 - 4) rather than (1 << 15 -1).

Fixes corruption to data uploaded with glBufferSubData.
