media: pt1: fix logic when pt1_nr_tables is zero or negative pt1_nr_tables is a modprobe parameter. The way the logic handles it, it can't be negative. However, user can set it to zero. If set to zero, however, it will cause troubles at pt1_init_tables(), as reported by smatch: drivers/media/pci/pt1/pt1.c:468 pt1_init_tables() error: uninitialized symbol 'first_pfn'.
