    Coverity fixes - 12023, 12024, and 12025
    
    . 12023 - Ignoring number of bytes read
      basicInit (ldclt.c):
      The return value from fread was ignored and not used for copying
      the read content from buffer to mctx.attrplFileContent.
    . 12024 - Resource leak
      roles_cache_create_object_from_entry (roles_cache.c):
      When an error occurred, filter_attr_value was not freed.
    . 12025 - Wrong sizeof argument
      read_metadata (dblayer.c):
      prfinfo is declared as PRFileInfo64, but when initializing the
      structure with NULL, the specified size was for PRFileInfo.
