[PATCH] Bluetooth: make hw_err static, reduces object code size

[Colin King]

From: Colin Ian King <colin.k...@canonical.com>

Don't populate the const array hw_err on the stack but instead make
it static. Makes the object code smaller by 45 bytes:

Before:
   text    data     bss     dec     hex filename
 100880   21090    1088  123058   1e0b2 linux/net/bluetooth/hci_core.o

After:
   text    data     bss     dec     hex filename
 100739   21186    1088  123013   1e085 linux/net/bluetooth/hci_core.o

(gcc version 8.2.0 x86_64)
