[bluez] Fix crash when connect to BT keyboard. Fixes JB#13213

hciops_encrypt_link() will be called when connect to BT keyboard.
In this function, "struct hci_conn_info" is used by
ioctl(dd, HCIGETCONNINFO, cr) to get information from linux kernel.
But Qcomm's kernel changed "struct hci_conn_info"'s definition,
thus caused this memory related crash.
