Hey everyone,

This simplifies the eventfd_signal() and eventfd_signal_mask() helpers
significantly. They can be made void and not take any unnecessary
arguments.

I've added a few more simplifications based on Sean's suggestion.

Changes in v2:
- further simplify helpers
- Link to v1: https://lore.kernel.org/r/20230713-vfs-eventfd-signal-v1-0-7fda6c5d212b@xxxxxxxxxx
