mips: clear fcc bits in fcsr after calling printf()

mips: clear fcc bits in fcsr after calling printf()

Clear floating point condition codes in the test after calling external
function (in this case printf), as it might have clobbered fcc bits in
fcsr.

This resolves  none/tests/mips64/round.c failure on some systems.

Patch by Aleksandra Karadzic.
