USB: gadget: storage gadgets send wrong error code for unknown commands
commit c85dcdac5852295cf6822f5c4331a6ddab72581f upstream.
This patch (as1539) fixes a minor bug in the mass-storage gadget
drivers. When an unknown command is received, the error code sent
back is "Invalid Field in CDB" rather than "Invalid Command". This is
because the bitmask of CDB bytes allowed to be nonzero is incorrect.
When handling an unknown command, we don't care which command bytes
are nonzero. All the bits in the mask should be set, not just eight
of them.
