i965: Fix glTexImage when packing alignment != cpp
Fixes texture corruption of Weston clients on cairo-glesv2 backend.
Commit 49ed599 introduced the bug.
Corruption occured when glTexSubImage called
intel_texsubimage_tiled_memcpy() with:
x,y=10,9
w,h=7,7
format=GL_ALPHA(0x1906)
type=GL_UNSIGNED_BYTE(0x1401)
gl_format=MESA_FORMAT_A8(0x18)
packing.alignemnt=4
The function miscalculated the source image's stride as w*cpp=7 without
taking into account the packing alignment. The actual stride was 8.
