Looking at ST SPEAr1340 AHCI code (the only user of the deprecated
pdata->suspend and pdata->resume) it is obvious the we should return
after calling pdata->suspend() only if the function have returned
non-zero return value. The code has been broken since commit 1e70c2
("ata/ahci_platform: Add clock framework support"). Fix it.
