IOCTLs are supposed to return 0 for success and negative error codes for
failure. Currently, this driver is returning 0 for failure and 1 for
success, that's not correct. Hence, fix it!

Closes: https://lore.kernel.org/all/YvzNg5ROnxEApDgS@kroah.com

Migrate the PCI endpoint test to Kselftest framework. All the tests that
were part of the previous pcitest.sh file were migrated.
Below is the exclusive list of tests:
1. BAR Tests (BAR0 to BAR5)
2. Legacy IRQ Tests
3. MSI Interrupt Tests (MSI1 to MSI32)
4. MSI-X Interrupt Tests (MSI-X1 to MSI-X2048)
5. Read Tests - MEMCPY (For 1, 1024, 1025, 1024000, 1024001 Bytes)
6. Write Tests - MEMCPY (For 1, 1024, 1025, 1024000, 1024001 Bytes)
7. Copy Tests - MEMCPY (For 1, 1024, 1025, 1024000, 1024001 Bytes)
8. Read Tests - DMA (For 1, 1024, 1025, 1024000, 1024001 Bytes)
9. Write Tests - DMA (For 1, 1024, 1025, 1024000, 1024001 Bytes)
10. Copy Tests - DMA (For 1, 1024, 1025, 1024000, 1024001 Bytes)
DMA and MEMCPY tests are added as fixture variants and can be executed
separately as below:
$ pci_endpoint_test -V dma (excluding DMA tests)
$ pci_endpoint_test -V memcpy (excluding MEMCPY tests)

+Testcase 10 (pci_ep_data_transfer.dma.COPY_TEST) will fail for most of the DMA

+controllers, it is advisable to skip the forementioned testcase using below
