Josh Poimboeuf 1402fd8ed7 objtool: Fix another switch table detection issue ...

Continue the switch table detection whack-a-mole.  Add a check to
distinguish KASAN data reads from switch data reads.  The switch jump
tables in .rodata have relocations associated with them.

This fixes the following warning:

  crypto/asymmetric_keys/x509_cert_parser.o: warning: objtool: x509_note_pkey_algo()+0xa4: sibling call from callable instruction with modified stack frame
