[MIPS,PATCH,committed] Fix mips.exp logic when disabling features removed in R6

[Matthew Fortune]

When switching up from an older ISA to MIPSR6 some features need to be
disabled. The support for this added in rev r225813 missed the fact
that both the $isa and $isa_rev variables are referenced in this code
so both must get redefined to their (potentially) new values. Without
this patch a number of tests will be reported as unsupported as it is
a TCL error not a test error.

Committed.

Thanks,
Matthew

	* gcc.target/mips/mips.exp (mips-dg-options): Redefine isa
	which is used in later code.
