Fix memory allocation check in aflpp custom mutators

Browse Source 
The memory allocation check in afl_custom_fuzz function was incorrect.
The condition was erroneously checking if ptr was non-null, whereas it
should return 0 when ptr is null. Correct the condition to properly
handle memory allocation failures.

Fixes: 32ffa266 ("max_len support")
