Gabe Black e81058c05b 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.
