PCI: Align checking of syscall user config accessors
[ Upstream commit ef9e4005cbaf022c6251263aa27836acccaef65d ]
After 34e3207205ef ("PCI: handle positive error codes"),
pci_user_read_config_*() and pci_user_write_config_*() return 0 or negative
errno values, not PCIBIOS_* values like PCIBIOS_SUCCESSFUL or
PCIBIOS_BAD_REGISTER_NUMBER.
Remove comparisons with PCIBIOS_SUCCESSFUL and check only for non-zero. It
happens that PCIBIOS_SUCCESSFUL is zero, so this is not a functional
change, but it aligns this code with the user accessors.
