usb: quirks: Add NO_LPM quirk for SanDisk Extreme 55AE
commit 19f795591947596b5b9efa86fd4b9058e45786e9 upstream.
This device exhibits I/O errors during file transfers due to unstable
link power management (LPM) behavior. The kernel logs show repeated
warm resets and eventual disconnection when LPM is enabled:
[ 3467.810740] hub 2-0:1.0: state 7 ports 6 chg 0000 evt 0020
[ 3467.810740] usb usb2-port5: do warm reset
[ 3467.866444] usb usb2-port5: not warm reset yet, waiting 50ms
[ 3467.907407] sd 0:0:0:0: [sda] tag#12 sense submit err -19
[ 3467.994423] usb usb2-port5: status 02c0, change 0001, 10.0 Gb/s
[ 3467.994453] usb 2-5: USB disconnect, device number 4
The error -19 (ENODEV) occurs when the device disappears during write
operations. Adding USB_QUIRK_NO_LPM disables link power management
for this specific device, resolving the stability issues.
