[PATCH][next] dma-buf/sw_sync: remove redundant error check on variable err

[Colin Ian King]

The variable err is always zero at the point where it is being
non-zero checked for an error. The check and error return path
are redundant and can be removed. Issue detected by Coverity Scan
static analysis.
