shared: drop redundant cryptsetup_enable_logging(NULL) calls (#41785)

These were only used to implicitly load libcryptsetup at startup.
dlopen_cryptsetup() now calls cryptsetup_enable_logging(NULL) itself,
and every code path that uses libcryptsetup calls dlopen_cryptsetup()
before doing so, so the upfront calls are no longer needed.
