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.
