[PATCH] scsi: hpsa: Fix missing error check for hpsa_scsi_do_simple_cmd_with_retry()

[Wentao Liang]

In the current implementation, the return value of
hpsa_scsi_do_simple_cmd_with_retry() is not checked. This can lead to
silent failures if the function fails, as the code would continue
execution and potentially use invalid error information.

This patch adds a check for the return value of
hpsa_scsi_do_simple_cmd_with_retry(). If the function fails, the error
is propagated to the caller, ensuring proper error handling.
