cli: fixed cli crash during volume set operation

PROBLEM:

The cli crashes in the following case:
gluster> volume set v3 auth.allow "write-behind"

CAUSE:

The second strncat operation in the last iteration of the for loop,
in cli_to_glusterd writes off the end of the space malloc'd for "cmd",
leading to memory corruption.

FIX:

Made the last strncat operation conditional so that in the last
iteration, strncat is avoided.
