Subject: storage/posix: Increment trusted.pgfid in posix_mknod

The value of trusted.pgfid.xx was always set to 1
in posix_mknod. This is incorrect if posix_mknod
calls posix_create_link_if_gfid_exists.

Change-Id: Ibe87ca6f155846b9a7c7abbfb1eb8b6a99a5eb68
fixes: bz#1623317

+# Test steps:
+# The test checks to make sure that the trusted.pgfid.xx xattr is set on
+# both the linkto and data files post the final rename.
+# The test creates files file-1 and file-3 so that src_hashed = dst_hashed,
+# src_cached = dst_cached and xxx_hashed != xxx_cached.
+# It then renames file-1 to file-3 which triggers the posix_mknod call
+# which updates the trusted.pgfid.xx xattr.
