net/ice: fix function pointer in multi-process

This patch uses the index value to call the function, instead of the function pointer assignment to save the selection of Receive Flex Descriptor profile ID.

Otherwise the secondary process will run with wrong function address from primary process.

Fixes 7a340b0b4e03 ("net/ice: refactor Rx FlexiMD handling")
