Revert "Fix data abort introduced by ef92ed4a."

This reverts commit 61a096499b72f82dd8efc782e30cfeb1a31ef400.

The original issue was caused by a new structure member which caused
bmp_args::buf to be unaligned for 2-byte reads. Enforcing that alignment
should be the faster fix. Aligning to cache (while at it) should
improve bmp loading times even more.
