MIPS: Correct ISA masking in FPU feature determination
Correct an ISA level determination problem introduced with 8b8aa636
[MIPS: kernel: cpu-probe.c: Add support for MIPS R6], reverting explicit
masking against individual `MIPS_CPU_ISA_*' macros in FPU feature
determination.
Feature macros such as `cpu_has_mips_r' cannot be used here, because
they operate on CPU #0 and we want to refer to the current CPU instead.
They cannot be used for masking against the current CPU either because
they mask against CPU #0 too, e.g.:
# define cpu_has_mips32r1 (cpu_data[0].isa_level & MIPS_CPU_ISA_M32R1)
