Remove a debug print in init_preload() which was left over from
development and isn't usefull at all currently. It was also causing
false positive test results.

Comparison of a boolean value (!__init_state) with a value of 2 (done)
as currently happens in the code is unlikely to succeed and causes
repeated initialization of the pthread function pointers.
Instead, remove boolean comparison so that we would initialize said
function pointers only once.

This makes initialization actually happen. Without it, initialization is
always skipped due to an incorrect conditional statement.

This allows lockdep to be used without being compiled in the
original program.
Usage is quite simple:
LD_PRELOAD=/path/to/liblockdep.so /path/to/my/program
And magically, you'll have lockdep checking in your program!
