tty: rocket: Fix possible buffer overwrite on register_PCI [ Upstream commit 0419056ec8fd01ddf5460d2dba0491aad22657dd ] If number of isa and pci boards exceed NUM_BOARDS on the path rp_init()->init_PCI()->register_PCI() then buffer overwrite occurs in register_PCI() on assign rcktpt_io_addr[i]. The patch adds check on upper bound for index of registered board in register_PCI. Found by Linux Driver Verification project (linuxtesting.org).
