memif: avoid double pool_put on a clib_file
When memif CP processes the socket connection error, it may go through
the following code paths which may eventually cause double pool_put on a
clib_file
memif_master_conn_fd_error:633 -> memif_disconnect ->
memif_socket_close -> memif_file_del_by_index ->
clib_file_del_by_index -> clib_file_del -> pool_put
After memif_master_conn_fd_error:633, the code continues on
memif_maser_conn_fd_error:651 -> memif_file_del -> clib_file_del ->
pool_put
The fix is to skip calling memif_file_del in
memif_master_conn_fd_error:651 if uf->file_descriptor == ~0 to catch
problem from all possible paths in memif_master_conn_fd_error
Type: fix
