ata_eh_analyze_serror() suppresses hotplug notifications if LPM is
being used because LPM generates spurious hotplug events. It compared
whether link->lpm_policy was different from ATA_LPM_MAX_POWER to
determine whether LPM is enabled; however, this is incorrect as for
drivers which don't implement LPM, lpm_policy is always
ATA_LPM_UNKNOWN. This disabled hotplug detection for all drivers
which don't implement LPM.
Fix it by comparing whether lpm_policy is greater than
ATA_LPM_MAX_POWER.

applied, though putting this into 2.6.38.1 is preferred to changing this
at -rc7... stable@ cc'd.
