hf mf chk bugfix and enhancements

[GoogleCodeExporter]

The command
hf mf chk *1 ? t keys.dic
currently always returns an "File reading error" on the last line. This patch 
fixes this issue.

I also made the default keys of the chk function more generic, so you do not 
need to adjust loop counters. To test this enhancement add or remove Keys to 
the default key array and run
hf mf chk *1 ? t

Bugfix:

Output before patch with dictionary:

proxmark3> hf mf chk *1 ? t keys.dic
chk custom key[0] a0a1a2a3a4a5          
chk custom key[1] b0b1b2b3b4b5          
chk custom key[2] 2a6d9205e7ca          
chk custom key[3] b8a1f613cf3d          
chk custom key[4] bedb604cc9d1          
chk custom key[5] b4c132439eef          
File reading error.
