    net/ice: add missing SMAC field mapping in flow input set

This patch fixes a bug where source MAC address matching in flow rules
was silently ignored. The ice_inset_map[] array was missing the mapping
entry for ICE_INSET_SMAC, causing flow rules that specified a source MAC
address to match any source address instead.

The patch looks correct. The missing ICE_INSET_SMAC entry in the
ice_inset_map[] array would indeed cause source MAC address matching to
fail silently. Adding the mapping entry resolves this issue.

The placement of the new entry immediately after ICE_INSET_DMAC maintains
logical ordering and aligns with the existing structure of the array.
