[PATCH] qbman: Remove set but not used variable 'err'

[Zheng Yongjun <zhengyongjun3@huawei.com>]

From: network <network@ubuntu.network>

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/soc/fsl/qbman/bman.c:640:6: warning: variable ‘err’ set but not used [-Wunused-but-set-variable]
  int err = 0;
      ^~~
err is never used, so remove it.
