aof.c: improve indentation and change warning message.

Related to #5201.

I removed the !!! Warning part since compared to the other errors, a
missing EXEC is in theory a normal happening in the AOF file, at least
in theory: may happen in a differnet number of situations, and it's
probably better to don't give the user the feeling that something really
bad happened.
