usb: dwc3: gadget: Remove redundant assignment to pointer trb

The pointer trb is being assigned a value that is not being
read afterwards, it is being re-assigned later inside a for_each_sg
loop. The assignment is redundant and can be removed.

Cleans up clang scan warning:
drivers/usb/dwc3/gadget.c:3432:19: warning: Value stored to 'trb'
during its initialization is never read [deadcode.DeadStores]
