NTB: hw: amd: fix an issue about leak system resources
[ Upstream commit 44a0a3c17919db1498cebb02ecf3cf4abc1ade7b ] The related system resources were not released when pci_set_dma_mask(), pci_set_consistent_dma_mask(), or pci_iomap() return error in the amd_ntb_init_pci() function. Add pci_release_regions() to fix it.
