Same iteration variable used for inner and outer loop

Inner loop was using same counter variable (i) as the outer loop, therefore
making outer loop terminate before it visited all of the ELF program segments.
Surrounding code in this inner loop clearly shows the intention that this loop
should not affect the outer one, therefore leading me to the conclusion that
this should be a bug an not expected code.

This bug was detected due to some other bug in ARC binutils that kept setting
TEXTREL for any PIE application.

Apart from the but, I have also moved the debug message inside of the TEXTREL
condition as mprotect is only really called if TELTREL is set.
