staging: vt6655: fix some erroneous memory clean-up loops

In the Linux kernel, the following vulnerability has been resolved:

staging: vt6655: fix some erroneous memory clean-up loops

In some initialization functions of this driver, memory is allocated with
'i' acting as an index variable and increasing from 0. The commit in
"Fixes" introduces some clean-up codes in case of allocation failure,
which free memory in reverse order with 'i' decreasing to 0. However,
there are some problems:
  - The case i=0 is left out. Thus memory is leaked.
  - In case memory allocation fails right from the start, the memory
    freeing loops will start with i=-1 and invalid memory locations will
    be accessed.

One of these loops has been fixed in commit c8ff91535880 ("staging:
vt6655: fix potential memory leak"). Fix the remaining erroneous loops.

CWE-401 Missing Release of Memory after Effective Lifetime

The product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse.
