[PATCH] lib: rhashtable: Correct self-assignment in rhashtable.c

[Rishabh Bhatnagar]

In file lib/rhashtable.c line 777, skip variable is assigned to
itself. The following error was observed:

lib/rhashtable.c:777:41: warning: explicitly assigning value of
variable of type 'int' to itself [-Wself-assign] error, forbidden
warning: rhashtable.c:777
This error was found when compiling with Clang 6.0. Change it to iter->skip.
