Since sata devices can take several seconds to recover the link on reset the 0.5 seconds that libsas currently waits may not be enough. Instead if we are rediscovering a phy that was previously attached to a sata device let libata handle any resets to encourage the device to transmit the initial fis. Once sas_ata_hard_reset() and lldds learn how to honor 'deadline' libsas should stop encountering phys in an intermediate state, until then this will loop until the fis is transmitted or ->attached_sas_addr gets cleared, but in the more likely initial discovery case we keep existing behavior.
