libata: fix probe_ent alloc/free bugs
ata_probe_ent_alloc() had a temporary hack such that devm_kzalloc()
was used for allocation if devres had been previously initialized on
the device; otherwise, plain kzalloc() was used. This was to make the
code useable from both the old and devres-aware libata drivers during
transition. This hack made ata_sas_port_alloc() unable to determine
how the probe_ent is allocated, causing double free in some cases.
Remove the now-unneeded hack and make ata_sas_port_alloc() use
devm_kfree().
