dma-buf: st: fix error handling in test_get_fences()
The new driver incorrectly unwinds after errors, as clang points out:
drivers/dma-buf/st-dma-resv.c:295:7: error: variable 'i' is used uninitialized whenever 'if' condition is true [-Werror,-Wsometimes-uninitialized]
if (r) {
^
drivers/dma-buf/st-dma-resv.c:336:9: note: uninitialized use occurs here
while (i--)
^
drivers/dma-buf/st-dma-resv.c:295:3: note: remove the 'if' if its condition is always false
if (r) {
^~~~~~~~
drivers/dma-buf/st-dma-resv.c:288:6: error: variable 'i' is used uninitialized whenever 'if' condition is true [-Werror,-Wsometimes-uninitialized]
if (r) {

drivers/dma-buf/st-dma-resv.c:336:9: note: uninitialized use occurs here
while (i--)
^
drivers/dma-buf/st-dma-resv.c:288:2: note: remove the 'if' if its condition is always false
if (r) {
^~~~~~~~
drivers/dma-buf/st-dma-resv.c:280:10: note: initialize the variable 'i' to silence this warning
int r, i;

= 0
Skip cleaning up the bits that have not been allocated at this point.
