libata: implement AC_ERR_NCQ
When an NCQ command fails, all commands in flight are aborted and the offending one is reported using log page 10h. Depending on controller characteristics and LLD implementation, all commands may appear as having a device error due to shared TF status making it hard to determine what's actually going on. This patch adds AC_ERR_NCQ, marks the command reported by log page 10h with it and print extra "<F>" after the error report for the command to help distinguishing the offending command.
