Kai-Heng Feng ac72e01a89 libata: Return correct status in sata_pmp_eh_recover_pm() when ATA_DFLAG_DETACH is set 
commit 8305f72f952cff21ce8109dc1ea4b321c8efc5af upstream.

During system resume from suspend, this can be observed on ASM1062 PMP
controller:

ata10.01: SATA link down (SStatus 0 SControl 330)
ata10.02: hard resetting link
ata10.02: SATA link down (SStatus 0 SControl 330)
ata10.00: configured for UDMA/133
Kernel panic - not syncing: stack-protector: Kernel
 in: sata_pmp_eh_recover+0xa2b/0xa40

CPU: 2 PID: 230 Comm: scsi_eh_9 Tainted: P OE
#49-Ubuntu
Hardware name: System manufacturer System Product

Kernel Offset: 0xcc00000 from 0xffffffff81000000
(relocation range: 0xffffffff80000000-0xffffffffbfffffff)

Since sata_pmp_eh_recover_pmp() doens't set rc when ATA_DFLAG_DETACH is
set, sata_pmp_eh_recover() continues to run. During retry it triggers
the stack protector.

Set correct rc in sata_pmp_eh_recover_pmp() to let sata_pmp_eh_recover()
jump to pmp_fail directly.
