ahci: Make sending the SETFEATURES_XFER command optional
This command doesn't really do anything when talking to a SATA device, and
sending it confuses some of them. This change makes sending the command
optional, and defaults to not. The situations where it should be sent are not
the common case.
With the standard SSD in the machine, here are some times with the option
turned off:
1. 8277
2. 8273
3. 8050
And turned on:
1. 8303
2. 8155
3. 8276
Sending that command seems to have no meaningful effect on performance.
This fixes problems with an SSD marked Toshiba NV6424, Taiwan 11159AE P
and TC58NVG5D2FTA10.
