libata-pmp-prep: implement qc_defer helpers
Implement ap->nr_active_links (the number of links with active qcs), ap->excl_link (pointer to link which can be used by ->qc_defer and is cleared when a qc with ATA_QCFLAG_CLEAR_EXCL completes), and ata_link_active(). These can be used by ->qc_defer() to implement proper command exclusion. This set of helpers seem enough for both sil24 (ATAPI exclusion needed) and cmd-switching PMP.
