[PATCH v2] nitro_enclaves: Fixup type and simplify logic of the poll mask setup

[Andra Paraschiv]

Update the assigned value of the poll result to be EPOLLHUP instead of
POLLHUP to match the __poll_t type.

While at it, simplify the logic of setting the mask result of the poll
function.

Changelog

v1 -> v2

* Simplify the mask setting logic from the poll function.
