The p9_client_clunk() function was called in one case by the
v9fs_fid_xattr_get() function during error handling even if the passed
variable "attr_fid" contained a null pointer.
Let us delete an unnecessary variable assignment there and return from
this implementation directly after a failure detection for
a p9_client_xattrwalk() call.
