Invalid C99 in source3/locking/brlock.c

[Albert Chin]

source3/locking/brlock.c has the following code:
        *br_lck = (struct byte_range_lock) {};

According to GCC -pedantic, this isn't standard-conforming (and the
Sun C compiler doesn't like it either). GCC warns with "warning: ISO C
forbids empty initializer braces". The fix is trivial. Just change to:
        *br_lck = (struct byte_range_lock) {{0}};

This occurs in master and v4-2-test.
