can: af_can: can_rcv_list_find(): fix kernel doc after variable renaming

This patch fixes the kernel doc for can_rcv_list_find() which was broken in commit:

    3ee6d2be ("can: af_can: rename find_rcv_list() to can_rcv_list_find()")

while renaming a variable, but forgetting to rename the kernel doc, too.
