crypto: api - Fix aligned ctx helper
The aligned ctx helper was using a bogus alignment value thas was
one off the correct value. Fortunately the current users do not
require anything beyond the natural alignment of the platform so
this hasn't caused a problem.
This patch fixes that and also removes the unnecessary minimum
check since if the alignment is less than the natural alignment
then the subsequent ALIGN operation should be a noop.
