PCI/P2PDMA: Fix incorrect pointer usage in devm_kfree() call
The error handling path in pci_p2pdma_add_resource() contains a bug in its
`pgmap_free` label.
Memory is allocated for the `p2p_pgmap` struct, and the pointer is stored
in `p2p_pgmap`. However, the error path calls devm_kfree() with `pgmap`,
which is a pointer to a member field within the `p2p_pgmap` struct, not the
base pointer of the allocation.
Correct the bug by passing the correct base pointer, `p2p_pgmap`, to
devm_kfree().
