KVM: arm64: Fix set_id_regs selftest for ASIDBITS becoming unwritable
In commit 03c7527e97f7 ("KVM: arm64: Do not allow ID_AA64MMFR0_EL1.ASIDbits
to be overridden") we made that bitfield in the ID registers unwritable
however the change neglected to make the corresponding update to set_id_regs
resulting in it failing:
ok 56 ID_AA64MMFR0_EL1_BIGEND
==== Test Assertion Failure ====
aarch64/set_id_regs.c:434: masks[idx] & ftr_bits[j].mask == ftr_bits[j].mask
pid=5566 tid=5566 errno=22 - Invalid argument

Remove ID_AA64MMFR1_EL1.ASIDBITS from the set of bitfields we test for
writeability.
