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")
