Browse Source 
There is a situation that getCurrentUsbFunctions callback function will
be invoked before mCurrentUsbFunctionsRequested flag updated, thus, gadget
will be reset during boot completed. Make sure mCurrentUsbFunctionsRequested
flag be updated before getCurrentUsbFunctions callback function invoked.

Test: Verified that gadget reset does not happen
