Fix section mismatch: ata_sff_exit

This build error showed up in linux-next tag next-20100820 for ia64:

WARNING: vmlinux.o(.init.text+0x4a952): Section mismatch in reference from the function ata_init() to the function .exit.text:ata_sff_exit() The function __init ata_init() references
a function __exit ata_sff_exit().
This is often seen when error handling in the init function
uses functionality in the exit path.
The fix is often to remove the __exit annotation of
ata_sff_exit() so it may be used outside an exit section.

Sure enough, dropping the __exit fixes the problem.

Tejun: I didn't pin down which commit broke this ... but you seem to have a number of recent commits here.

It's the scsi transport addition. It adds an init failure case where ata_sff_exit() is called to undo initialization, so your fix is correct.

Thanks.
