RDMA/hfi1: Use RMW accessors for changing LNKCTL2

Convert open coded RMW accesses for LNKCTL2 to use
pcie_capability_clear_and_set_word() which makes its easier to
understand what the code tries to do.

In addition, this futureproofs the code. LNKCTL2 is not really owned by
any driver because it is a collection of control bits that PCI core
might need to touch. RMW accessors already have support for proper
locking for a selected set of registers to avoid losing concurrent
updates (LNKCTL2 is not yet among the registers that need protection
but likely will be in the future).
