  Changed paths:

    M llvm/test/MC/RISCV/option-invalid.s

  Log Message:
  -----------
  [RISCV] Don't persist invalid feature state on .option arch error

Otherwise subsequent .option arch, +foo directives (but not -, since
those have their own separate validation) fail the parseFeatureBits
check, leading to cascading errors.
