[compiler-rt] Fix diagnostic in InstrProfError 

This patch fixes some issues introduced in
https://reviews.llvm.org/D108942:

1) Remove the default label to fix the bots that use
-Werror,-Wcovered-switch-default
2) Modify the malformed test to fix the bots that are
built without zlib support
3) Modify some error messages in malformed profiles
