[PATCH] net: usb: qmi_wwan: constify attribute_group structures.

[Arvind Yadav]

attribute_groups are not supposed to change at runtime. All functions
working with attribute_groups provided by <linux/netdevice.h> work
with const attribute_group. So mark the non-const structs as const.

File size before:
   text    data     bss     dec     hex filename
  16831     464       0   17295    438f drivers/net/usb/qmi_wwan.o

File size After adding 'const':
   text    data     bss     dec     hex filename
  16895     400       0   17295    438f drivers/net/usb/qmi_wwan.o
