patch for ls_oci8.c in luasql-2.0.0

[Klaus Ripke <paul-lua@...>]

hi

in luasql-2.0.0, ls_oci8.c, free_column_buffers() has a line 251
reading "case SQLT_NUM: /* NUM is an array of char */"
resulting in a free on the char *s of union column_value.

Well, since SQLT_NUM is *not* an array of char in this
implementation (and this file uses the union's double
value in a couple of other places for SQLT_NUM),
this crashes occasionally on cursor close.

This case must be moved a line up next to case SQLT_FLT,
which does not free zilch, then everything's fine.
