[PATCH] USB: storage: include US_FL_NO_SAME in quirks mask

[Xu Rao]

usb_stor_adjust_quirks() parses the usb-storage.quirks module
parameter into a new flag set and then applies it with the quirk
mask to override built-in flags.

The mask is meant to cover the flags that can be overridden by
the module parameter. The 'k' quirk character sets US_FL_NO_SAME,
but US_FL_NO_SAME is not included in the mask.

As a result, the module parameter can set US_FL_NO_SAME, but it
cannot clear a built-in US_FL_NO_SAME flag by providing an override
entry that omits 'k'.

Add US_FL_NO_SAME to the mask so that the module parameter can
override it in the same way as the other supported flags.
