main.c: Fix undefined value for cur

As otherwise reported by clang 14.0.0:

main.c:679:14: warning: variable 'cur' is used uninitialized whenever '&&' condition is false [-Wsometimes-uninitialized]
    else if (available && quota_current(a, username, &cur))

This was a minor issue after all, as pq was not used unless available
were set.
