gfapi: new inode created in glfs_resolve_component even if inode is in inode table
Backport of http://review.gluster.org/#/c/9253/
problem: USS allows split-brain file to be accessed while main volume
gives I/O error.
cause:
AFR detects split-brain on lookup. It stores this information in
inode context. open and readv fop checks this flag from inode context.
open and readv fop fails if split-brain flag is set for the file.
USS uses gfapi to access snapshot volume. During open call
gfapi internally calls glfs_resolve_component. glfs_resolve_component
generates a new inode even if inode is present for the file.
Because of which afr_lookup acts on a new inode which does not
contain the split-brain flag.
