e100: fix typo in MDI/MDI-X eeprom check in e100_phy_init

Although it doesn't explicitly say so, commit 60ffa478759f39a2 ("e100:
Fix MDIO/MDIO-X") appears to be intended to revert the earlier commit
648951451e6d2d53 ("e100: fixed e100 MDI/MDI-X issues").  However,
careful examination reveals that the attempted revert actually
_inverted_ the test for eeprom_mdix_enabled.  That is bound to program
a few PHYs incorrectly...
