sfc: Fix test for MDIO read failure

Commit 27dd2caca4eabe7c13a052b7456495ba75535e6a changed
mdio_clause45_check_mmds() to read both DEVS0 and DEVS1 registers and
to combine their values into an unsigned 32-bit mask.  This made the
following test for a negative (failure) value useless.  Fix it to
check whether either read failed.
