net: wireless: make a const array static, makes object smaller
Don't populate the const array bws on the stack but instead it
static. Makes the object code smaller by 80 bytes:
Before:
text data bss dec hex filename
85694 16865 1216 103775 1955f ./net/wireless/reg.o
After:
text data bss dec hex filename
85518 16961 1216 103695 1950f ./net/wireless/reg.o
(gcc version 10.2.0)
