mlxsw: spectrum_dpipe: Add missing error path
[ Upstream commit 3a99cbb6fa7bca1995586ec2dc21b0368aad4937 ]
In case devlink_dpipe_entry_ctx_prepare() failed, release RTNL that was
previously taken and free the memory allocated by
mlxsw_sp_erif_entry_prepare().
Fixes: 2ba5999f009d ("mlxsw: spectrum: Add Support for erif table entries access")
