[PATCH] extcon: add index increment in find_cable_index_by_name

[Tim Bird <tim.bird@sonymobile.com>]

This fixes a bug introduced by commit 73b6ecdb93e8 ("extcon: Redefine the
unique id of supported external connectors without 'enum extcon' type")
which introduced an infinite loop in find_cable_index_by_name.  That commit
converted the scan from a for loop to a while, but did not increment
'i' anywhere in the loop.  If the loop index is not incremented, the
function never exits.

This function can never work correctly without this fix.
