NPC transmit side mcam rules can use the pcifunc (in packet metadata
added by hardware) of transmitting device for mcam lookup similar to
the channel of receiving device at receive side.
The commit 18603683d766 ("octeontx2-af: Remove channel verification
while installing MCAM rules") removed the receive side channel
verification to save hardware MCAM filters while switching packets
across interfaces but missed removing transmit side checks.
This patch removes transmit side rules validation.
