Subject: [PATCH] scsi: libsas: fix error when getting phy events

commit 2b23d9509fd7174b362482cf5f3b5f9a2265bc33 upstream.

The intend purpose here was to goto out if smp_execute_task() returned
error. Obviously something got screwed up. We will never get these link
error statistics below:

~:/sys/class/sas_phy/phy-1:0:12 # cat invalid_dword_count
0
~:/sys/class/sas_phy/phy-1:0:12 # cat running_disparity_error_count
0
~:/sys/class/sas_phy/phy-1:0:12 # cat loss_of_dword_sync_count
0
~:/sys/class/sas_phy/phy-1:0:12 # cat phy_reset_problem_count
0

Obviously we should goto error handler if smp_execute_task() returns
non-zero.
