tests: net: socket: udp: clear control data buffer before recvmsg

Browse source 
Currently, the test doesn't clear the control data buffer before
calling recvmsg. This leads to recvmsg being unable to add the new
control data, which corresponds to the current received data.
This commit aims to clear the control data buffer to match most use
cases, when the control data buffer is empty before calling recvmsg.
