Subject: [PATCH] mtd: nand: denali_pci: add missing pci_release_regions() calls

The probe function calls pci_request_regions(), but I do not see
corresponding pci_release_regions() calls.

While we are here, rename the jump labels to follow the guideline
"Choose label names which say what the goto does" suggested by
Documentation/CodingStyle.
