libata: init ata_print_id to 0
When comparing the dmesg between 3.4-rc3 and 3.4-rc4 I found the
following differences:
-ata1: SATA max UDMA/133 abar m2048@0xf9fff000 port 0xf9fff100 irq 47
-ata2: SATA max UDMA/133 abar m2048@0xf9fff000 port 0xf9fff180 irq 47
-ata3: DUMMY
+ata2: SATA max UDMA/133 abar m2048@0xf9fff000 port 0xf9fff100 irq 47
+ata3: SATA max UDMA/133 abar m2048@0xf9fff000 port 0xf9fff180 irq 47
ata4: DUMMY
ata5: DUMMY
-ata6: SATA max UDMA/133 abar m2048@0xf9fff000 port 0xf9fff380 irq 47
+ata6: DUMMY
+ata7: SATA max UDMA/133 abar m2048@0xf9fff000 port 0xf9fff380 irq 47
The change of numbering comes from commit 85d6725b7c0d7e3f ("libata:
make ata_print_id atomic") that changed lines like
ap->print_id = ata_print_id++;
to
ap->print_id = atomic_inc_return(&ata_print_id);
As the latter behaves like ++ata_print_id, we must initialize
it to zero to start the numbering from one.
