[PATCH] libmultipath:fix loop traversed partly

[zhang.kai16@zte.com.cn]

From: "zhang.kai" <zhang.kai16@zte.com.cn>

Problem:
With each iteration of the vector_foreach_slot() loop statement,
some slots couldn't be traversed when a slot is deleted from vector.

Reasons:
Currently,loop's index 'i' is not decremented correspondingly when a slot is
deleted from vector.Meanwhile, in the vector_foreach_slot() loop, mpp is assigned
from vector newmp directly, so find_slot() could be omitted.
