[svn-r16676] #1521 (B2) H5DSdetach_scale memory leak
ISSUE: Purify (Windows Visual Studio 6) complains of a memory leak in H5DSdetach_scale call regarding a H5Aread call (stack is H5A_read, H5T_convert, H5T_conv_vlen, H5T_vlen_seq_mem_write, H5MM_malloc). SOLUTION: When a scale is detached from a dataset, the variable length structure length field is decreased in one entry. The associated pointer must be reallocated with the new length. DOCS AND TEST: Nothing added tested: windows with purify, linux
