devlink: hold region lock when flushing snapshots

Netdevsim triggers a splat on reload, when it destroys regions
with snapshots pending:

WARNING: CPU: 1 PID: 787 at net/core/devlink.c:6291 devlink_region_snapshot_del+0x12e/0x140
CPU: 1 PID: 787 Comm: devlink Not tainted 6.1.0-07460-g7ae9888d6e1c #580
RIP: 0010:devlink_region_snapshot_del+0x12e/0x140
Call Trace:
<TASK>

This is the locking assert in devlink_region_snapshot_del(),
we're supposed to be holding the region->snapshot_lock here.
