quota: allow usage of getrpcbynumber() instead of getrpcbynumber_r()

allow usage of getrpcbynumber() instead of getrpcbynumber_r()

libtirpc does not implement the reentrant function getrpcbynumber_r(),

so allow quota to use the non-reentrant version getrpcbynumber(). This

should not be a problem as quota tools are not multi-threaded.
