[PATCH] libata: Apply NOLPM quirk for SanDisk SD7UB3Q*G1001 SSDs

From: Hans de Goede
Date: Thu Apr 26 2018 - 16:32:30 EST

Richard Jones has reported that using med_power_with_dipm on a T450s
with a Sandisk SD7UB3Q256G1001 SSD (firmware version X2180501) is
causing the machine to hang.

Switching the LPM to max_performance fixes this, so it seems that
this Sandisk SSD does not handle LPM well.

Note in the past there have been bug-reports about the following
Sandisk models not working with min_power, so we may need to extend
the quirk list in the future: name - firmware
Sandisk SD6SB2M512G1022I - X210400
Sandisk SD6PP4M-256G-1006 - A200906
