Revert "VNX: Set timeout for naviseccli"

Revert "VNX: Set timeout for naviseccli"

EMC CI test failed.
It is not the fault of adding timeout option to naviseccli.
I made a mistake by adding wrong option format in code.
The command line should be
self.command = (navisecclipath, '-timeout', '120', '-address')
instead of
self.command = (navisecclipath, '-timeout 120', '-address')
Later, I will send out a new review for the right one,
after this is reverted.

This reverts commit 4fe875a199e407970686d6f4159e5f15de0528db.
