libata: fix handling of port actions in per-dev action mask
libata EH ignores port-wide actions in per-dev action mask. However,
device resume requests EH_SOFTRESET using per-dev action mask. Under
certain circumstances, this results in not resetting frozen port after
resuming which causes failure of all commands.
This patch allows port-wide actions to be requested in per-dev action
mask. Before EH recovery starts, port-wide actions will be collected.
