staging: rdma: hfi1: chip: Remove wrapper function

Drop wrapper function remap_receive_available_interrupt() that wraps a
call to remap_intr() with the only difference being the addition of
macro IS_RCVAVAIL_START to the second argument of remap_intr().

Both the function names give the same information so the wrapper
function can be dropped.
