api: fix rx timeout thread busy loop after reconnect

After memclnt api client disconnect, read timeout is set to zero
and stays the same even after same client reconnect. It causes
client process to spin in timeout loop up to 100% cpu.
Fix it by resetting timeout process state upon every (re)connect.

Type: fix
