fix Suspicious code in j2k.c #517

[renevanderark]

Okay, so this is my very first pull request, removing the apparently superfluous call in line 10024 opj_alloc_tile_component_data(l_tilec);

I tested this manually and reran the regression tests encountering no apparent differences. Please be gentle on feedback as I'm quite new to collaborating on github.
