usb: gadget: configfs: clear deactivation flag in configfs_composite_unbind()
If any function like UVC is deactivating gadget as part of composition switch which results in not calling pullup enablement, it is not getting enabled after switch to new composition due to this deactivation flag not cleared. This results in USB enumeration not happening after switch to new USB composition. Hence clear deactivation flag inside gadget structure in configfs_composite_unbind() before switch to new USB composition.
