doc: fix event timer adapter guide

[ upstream commit 4109d71 ]

In the example:
* Properly initialize the socket id field.
* Remove comments redundant and/or not consistent with the code. 180
  seconds is not 2 minutes.
* Remove redundant pointer initialization.

In both the example and text, the flags field of the conf struct was
erroneously referred to as timer_adapter_flags and the max_tmo_ns
field as max_tmo_nsec.
