[PATCH v2] block: remove never-modified global variable

From: Brian Norris
Date: Wed May 20 2015 - 20:32:47 EST


AFAICT, 'warn_no_part' never takes (and never has? at least, not in the
git history) taken a value besides 1. It also has a disgruntled warning
comment next to it, suggesting it shouldn't be there at all.

While removing the 'warn_no_part' check, let's combine a pair of string
cat/print into a single print, and reduce the err/res logic to something
simpler.

v2:
- combine the cat/print lines
- simplify the err/res logic
