[PATCH] extcon: Fix kernel hang for find_cable_index_by_name() users

[Roger Quadros]

Users of find_cable_index_by_name() will cause a kernel hang
as the while loop counter is never incremented and end condition
is never reached.

Fixes: commit 73b6ecdb93e8 ("extcon: Redefine the unique id of supported external connectors without 'enum extcon' type")
