Subject: [PATCH] configure: Fix the nasm version detection.

I used the nasm with unstable version while compiling SPDK with ISA-L.
And when running nasm -v, it shows:

NASM version 2.16rc0 compiled on May 27 2021

So the version checking in the script is not correct,
it will get "2.16rc0", but not "2.16".  Then the version comparison
will fail.

This patch will fix such issue when users use an unstable nasm and it
also works for the stable version.
