MIPS: Remove r6 DCHECKs for NEG.fmt instruction

These DCHECKs were causing several test failures or r6. They should not
be here because only NEG.PS format was removed in r6, NEG.S and NEG.D
instructions remain.

No L-G-T-M from a valid reviewer yet. 
CQ run can only be started by full committers or once the patch has
received an L-G-T-M from a full committer.
Even if an L-G-T-M may have been provided, it was from a non-committer,
_not_ a full super star committer.
Committers are members of the group "project-v8-committers".
Note that this has nothing to do with OWNERS files.
