MIPS: Remove invalid check

Unsigned values cannot be lesser than zero.

The problem has been detected using proposed semantic patch
scripts/coccinelle/tests/unsigned_lesser_than_zero.cocci [1].

[ralf@linux-mips.org: Chris Dearman's original commit
9318c51a ([MIPS] MIPS32/MIPS64 secondary
cache management) introduced these less than zero checks in 2.6.18.]
