HID: elan: Make array buf static, shrinks object size
Don't populate the array buf on the stack but instead make it
static. Makes the object code smaller by 43 bytes:
Before:
text data bss dec hex filename
7769 1520 0 9289 2449 drivers/hid/hid-elan.o
After:
text data bss dec hex filename
7662 1584 0 9246 241e drivers/hid/hid-elan.o
(gcc version 8.2.0 x86_64)
