pw_async2_epoll: Fix block on racing wakeups

The notify_fd_ must be nonblocking in order to ensure that the
wakeup write call never blocks, even when several racing wake
attempts fill the pipe.

Pigweed

Pigweed is an open source collection of embedded-targeted libraries–or as we like to call them, modules. These modules are building blocks and infrastructure that enable faster and more reliable development on small-footprint MMU-less 32-bit microcontrollers like the STMicroelectronics STM32L452 or the Nordic nRF52832.

For more information please see our website: https://pigweed.dev/.
