Bug#25213 - Compiler warnings in MyISAM code 

Compiler warnings due to non-matching conversion
specifications in format strings in DBUG_PRINT calls,
due to non-used parameters (in non-debug mode), and
due to seemingly uninitialized variables.

Initialized variables, declared parameters unused, and
casted DBUG_PRINT arguments to get rid of warnings.
