net: marvell: prestera: fix NULL dereference on devlink_alloc() failure
[ Upstream commit a428e0da1248c353557970848994f35fd3f005e2 ]
devlink_alloc() may return NULL on allocation failure, but
prestera_devlink_alloc() unconditionally calls devlink_priv() on
the returned pointer.
This leads to a NULL pointer dereference if devlink allocation fails.
Add a check for a NULL devlink pointer and return NULL early to avoid
the crash.
