usb: gadget: f_mtp: Avoid race between mtp_read and mtp_function_disable
While mtp_read is being executed and mtp_function_disable
is called then all the eps will be disabled which will
lead to NULL pointer dereference in usb_ep_align_maybe
function which will subsequently try to access endpoint
descriptors.
Add spinlock protection in mtp_function_disable to
avoid race between mtp_read and mtp_function_disable.
