Merge branch 'mlxsw-spectrum_span-Two-minor-adjustments'

Ido Schimmel says:

====================
mlxsw: spectrum_span: Two minor adjustments

Petr says:

This patch set fixes a couple of nits in mlxsw's SPAN implementation:
two counts of inaccurate variable name and one count of unsuitable error
code, fixed, respectively, in patches #1 and #2.
