net: pcs: xpcs: propagate xpcs_read error to xpcs_get_state_c37_sgmii

While phylink_pcs_ops :: pcs_get_state does return void, xpcs_get_state()
does check for a non-zero return code from xpcs_get_state_c37_sgmii()
and prints that as a message to the kernel log.

However, a non-zero return code from xpcs_read() is translated into
"return false" (i.e. zero as int) and the I/O error is therefore not
printed. Fix that.
