Don't populate the array extension_sig on the stack but instead make it
static. Makes the object code smaller by 59 bytes:
Before:
text data bss dec hex filename
14366 4920 0 19286 4b56 linux/drivers/bluetooth/btrtl.o
After:
text data bss dec hex filename
14243 4984 0 19227 4b1b linux/drivers/bluetooth/btrtl.o
(gcc version 8.2.0 x86_64)
