Greg Kroah-Hartman f08adf5add USB: gadget: bRequestType is a bitfield, not a enum 
Szymon rightly pointed out that the previous check for the endpoint
direction in bRequestType was not looking at only the bit involved, but
rather the whole value.  Normally this is ok, but for some request
types, bits other than bit 8 could be set and the check for the endpoint
length could not stall correctly.

Fix that up by only checking the single bit.

Fixes: 153a2d7e33 ("USB: gadget: detect too-big endpoint 0 requests")
