network: check negative values in bridge queues

Browse Source 
We already are checking for negative value, reporting an error, but
using wrong function and the check only succeeds when a value that
cannot be converted to number successfully is encountered. This patch
provides just a minor change in call of the right version
of function virStrToLong.

Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1138539
