openvzGetProcessInfo: address clang-detected low-probability flaw
openvzGetProcessInfo: address clang-detected low-probability flaw

* src/openvz/openvz_driver.c (openvzGetProcessInfo): Reorganize
so that unexpected /proc/vz/vestat content cannot make us use
uninitialized variables.  Without this change, an input line with
a matching "readvps", but fewer than 4 numbers would result in our
using at least "systime" uninitialized.
