Fix: ring_buffer_frontend.c: init read timer with uninitialized flags

For the config->alloc RING_BUFFER_ALLOC_GLOBAL (metadata channel), the
read timer flags argument is uninitialized.

Found by Coverity:
CID 1401114 (#1 of 1): Uninitialized scalar variable (UNINIT)
6. uninit_use_in_call: Using uninitialized value flags when calling init_timer_key.
