rx: Add 'getters' for Rx timeout values
Since
aa76c8f67001 'rx: Make struct rx_connection private', the fields
in struct rx_connection have been non-public.
In preparation for a future commit, implement new 'getter' routines for
the three rx_connection timeout values. Each one is fashioned after the
pre-existing 'setters':
- rx_GetConnDeadTime()
- rx_GetConnIdleDeadTime()
- rx_GetConnHardDeadTime()
