[PATCH] build fix for lvm with gcc 4

Reported by Marco Gatti :

I decided to upgrade from 2.4.34 to 2.4.35 in one of my servers but i
encountered a compile problem:

lvm.c:397: error: static declaration of 'vg_count' follows non-static
declaration
lvm-internal.h:48: error: previous declaration of 'vg_count' was here

I know this was an already fixed bug but now it seems to come out again
compiling 2.4.35 vanilla with gcc version 4.1.3 20070629 (prerelease) (Debian
4.1.2-13). 2.4.34.6 vanilla compiled fine.

Simple fix below tested and confirmed by Marco.
