HID: asus: make array 'buf' static const
Don't populate the const read-only array 'buf' on the stack but instead
make it static. Makes the object code smaller by 26 bytes:
Before:
text data bss dec hex filename
14378 2384 64 16826 41ba linux/drivers/hid/hid-asus.o
After:
text data bss dec hex filename
14296 2440 64 16800 41a0 linux/drivers/hid/hid-asus.o
(gcc version 7.2.0 x86_64)
[jkosina@suse.cz: change commit message slightly]
