description:
lint: rename dinfo_t.d_stralign to d_sou_align_in_bits

When talking about alignment, offset and size of a type, the measurement
unit must be mentioned in the variable name, especially when it differs
from the standard unit of measurement, which is a byte, not a bit.

No functional change.
