libata: fix error checking in in ata_parse_force_one()
[ Upstream commit f7cf69ae171592d133c69b9adaa5de7cfb6038ea ]
ata_parse_force_one() was incorrectly comparing @p to @endp when it
should have been comparing @id. The only consequence is that it may
end up using an invalid port number in "libata.force" module param
instead of rejecting it.
