Bluetooth: L2CAP: Fix build errors in some archs
commit b840304fb46cdf7012722f456bce06f151b3e81b upstream.
This attempts to fix the follow errors:
In function 'memcmp',
inlined from 'bacmp' at ./include/net/bluetooth/bluetooth.h:347:9,
inlined from 'l2cap_global_chan_by_psm' at
net/bluetooth/l2cap_core.c:2003:15:
./include/linux/fortify-string.h:44:33: error: '__builtin_memcmp'
specified bound 6 exceeds source size 0 [-Werror=stringop-overread]
44 | #define __underlying_memcmp __builtin_memcmp
| ^
./include/linux/fortify-string.h:420:16: note: in expansion of macro
'__underlying_memcmp'
420 | return __underlying_memcmp(p, q, size);
| ^~~~~~~~~~~~~~~~~~~
