[svn-r19832] Bug fix - In the code of N-bit filter, one line (the last line of H5Znbit.c in H5Z_nbit_compress - 
"*buffer_size = j + 1;" was mistakenly taken out by someone.  It is necessary to update the new size.  I
put it back and made 2 test cases for integer and float to verify the correct dataset size.

Tested on jam, heiwa, and amani.
