vasnprintf: silence mingw compiler warning
On mingw, vasnprintf is able to use snprintf, but not its return
value; this led to a situation where gcc warns:
vasnprintf.c: In function 'vasnprintf':
vasnprintf.c:4609:21: error: variable 'has_width' set but not used [-Werror=unused-but-set-variable]
Rather than hacking through a bunch of #ifdefs, where some used both
variables and others only used one, I changed the lone use of just
'width' to also use 'has_width'.
* lib/vasnprintf.c (VASNPRINTF): Avoid unused variable warning.
