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.
Fixes: a1b3695820aa ("NTB: Add support for AMD PCI-Express Non-Transparent Bridge")
