net: encx24j600: Add parentheses to fix precedence

In functions regmap_encx24j600_phy_reg_read() and
regmap_encx24j600_phy_reg_write() in the conditions of the waiting
cycles for filling the variable 'ret' it is necessary to add parentheses
to prevent wrong assignment due to logical operations precedence.
