scsi: pm80xx: Fix for SATA device discovery

[ Upstream commit ce21c63ee995b7a8b7b81245f2cee521f8c3c220 ]

Driver was missing complete() call in mpi_sata_completion which result in
SATA abort error handling timing out. That causes the device to be left in
the in_recovery state so subsequent commands sent to the device fail and
the OS removes access to it.
