util/nvmutil: remove the swap() function

directly handle swapping in word and set_word

in my testing, x86_64 and arm64 compilers actually produce
more efficient code this way. i previously only did a big
swap on the whole buffer on big-endian CPUs, and directly
accessed without swaps on little-endian, as an optimisation.

however, the old code is actually slower than what the
compiler produces, with the new code!

portability is retained with big-endian host CPUs and
little-endian host CPUs.

this also avoids the complication of memcpy and is just
generally extremely reliable by comparison.
