  fuzz/provider.c: check evp##_up_ref return value in collect_##evp

Coverity has reported an unchecked result of an evp##_up_ref call
that is checked elsewhere.  Rewrite the collect routine to try to do
the up_ref first, and then call free if push doesn't succeed.

  -----------
  crypto/pem/pem_info.c: avoid switching on PEM_INFO_NONE

Coverity complains that the switch statements in PEM_X509_INFO_read_bio_ex()
switches on PEM_INFO_NONE, while the enclosing condition
(itype != PEM_INFO_NONE) explicitly rules it out.  Pacify it by changing
the switch case to default (not removing it to avoid triggering
-Werror=switch).
