scsi: megaraid_sas: Fix crash after a double completion

[ Upstream commit 2309df27111a51734cb9240b4d3c25f2f3c6ab06 ]

When a physical disk is attached directly "without JBOD MAP support" (see
megasas_get_tm_devhandle()) then there is no real error handling in the
driver.  Return FAILED instead of SUCCESS.
