libata-eh: fix slave link EH action mask handling

Browse Source 
Slave link action mask is transferred to master link and all the EH
actions are taken by the master link.  ata_eh_about_to_do() and
ata_eh_done() are called with ATA_EH_ALL_ACTIONS to clear the slave
link actions during transfer.  This always sets ATA_PFLAG_RECOVERED
flag causing spurious "EH complete" messages.

Don't set ATA_PFLAG_RECOVERED for slave link actions.
