This patch removes hfi1_nomsix() wrapper function that is used to wrap
pci_disable_msix() and so substituted the wrapper function by a direct
call to pci_disable_msix().

Drop wrapper functions sdma_start_err_halt_wait() and
sdma_start_sw_clean_up() that can be replaced by a direct call to
schedule_work() and tasklet_hi_schedule() respectively both of which
are standard kernel functions.

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.
