net: ieee802154: atusb: Replace GFP_ATOMIC with GFP_KERNEL in atusb_probe
atusb_probe() is never called in atomic context.
This function is only set as ".probe" in struct usb_driver.
Despite never getting called from atomic context,
atusb_probe() calls usb_alloc_urb() with GFP_ATOMIC,
which does not sleep for allocation.
GFP_ATOMIC is not necessary and can be replaced with GFP_KERNEL,
which can sleep and improve the possibility of sucessful allocation.
This is found by a static analysis tool named DCNS written by myself.
And I also manually check it.
