Subject: mlxsw: spectrum_span: Use a more fitting error code
Patch-mainline: v4.18-rc1
Git-commit: c41c0dd7a641cb28f7239e7086419741af78c448
References: bsc#1112374

ENOENT is suitable when an item is looked for in a collection and can't
be found. The failure here is actually a depletion of a resource, where
ENOBUFS is the more fitting error code.
