octeontx2: cn10k: fix RX flowid TCAM mask handling

Browse source

[ Upstream commit ab9b218a15 ]

The RX flowid programming initializes the TCAM mask to all ones, but
then overwrites it when clearing the MAC DA mask bits. This results
in losing the intended initialization and may affect other match fields.

Update the code to clear the MAC DA bits using an AND operation, making
the handling of mask[0] consistent with mask[1], where the field-specific
bits are cleared after initializing the mask to ~0ULL.
