net: stmmac: Remove unneeded I/O read caught by cppcheck
Cppcheck found a case where a local variable was being assigned a value,
but not used. There seems to be no reason to read this register before
assigning a new value, so addressing thie issue.
cppcheck --force --enable=all --inline-suppr . shows ...
Variable 'value' is reassigned a value before the old one has been used.
