scsi: hpsa: Fix error handling in hpsa_add_sas_host()
hpsa_sas_port_add_phy() does:
...
sas_phy_add() -> may return error here
sas_port_add_phy()
...
Whereas hpsa_free_sas_phy() does:
...
sas_port_delete_phy()
sas_phy_delete()
...
If hpsa_sas_port_add_phy() returns an error, hpsa_free_sas_phy() can not be
called to free the memory because the port and the phy have not been added
yet.
Replace hpsa_free_sas_phy() with sas_phy_free() and kfree() to avoid kernel
crash in this case.
Fixes: d04e62b9d63a ("hpsa: add in sas transport class")
