RDMA/rxe: Remove pkey table
The RoCE spec requires RoCE devices to support only the default pkey.
However the rxe driver maintains a 64 enties pkey table and uses only the
first entry. Remove the pkey table and hard code a table of length one
hard wired with the default pkey. Replace all checks of the pkey_table
with a comparison to the default_pkey instead.
