[ Upstream commit 4e3c7c00bba0636b97eb23d582c20b0f5d95ce20 ]
Fixes gcc '-Wunused-but-set-variable' warning:
drivers/net/ethernet/aquantia/atlantic/hw_atl/hw_atl_utils.c:260:7: warning: variable 'err' set but not used [-Wunused-but-set-variable]
'err' should be returned while set MPI_DEINIT state fails in hw_atl_utils_soft_reset.
