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
