IB/qib: Use pcie_set_mps() and pcie_get_mps() to simplify code

Browse source

Refactor qib_tune_pcie_caps().  Use pcie_get_mps(), pcie_set_mps(),
pcie_get_readrq(), and pcie_set_readrq() to simplify the code.  The PCI
core caches the "PCIe Max Payload Size Supported" in pci_dev->pcie_mpss,
so use that instead of pcie_capability_read_word().  Remove the unused
val2fld() and fld2val().
