Counter part of mfi driver commit in mrsas
Switch from make_dev_alias to make_dev_alias_p since make_dev_alias_p can gracefully fail if the /dev/megaraid_sas_ioctl_node symlink already exists. This can happen if mfi(4) and mrsas(4) are both attached to cards and providing Linux emulation support. Let the first one win. An equivalent change has been done in mfi(4). Extra credit would be to pass the Linux emulation call to the other driver when appropriate. This will probably be a rare case and the user can manually change where the symlink points to. MFC after: 3 days
