IB/ipath: Fix PCI config write size used to clear linkctrl error bits
In slave_or_pri_blk(), pci_write_config_byte() is used to write a 16-bit quantity to clear linkctrl CRC error bits. This is clearly a bug and also causes the warning drivers/infiniband/hw/ipath/ipath_iba6110.c: In function 'slave_or_pri_blk': drivers/infiniband/hw/ipath/ipath_iba6110.c:849: warning: overflow in implicit constant conversion Fix this by using pci_write_config_word() instead.
