of: Fix of_find_node_opts_by_path() handling of alias+path+options
of_find_node_opts_by_path() fails to find OF device node when its
@path parameter have pattern below:
"alias-name/node-name-1/.../node-name-N:options".
The reason is that alias name length calculated by the API is wrong, as
explained by example below:
"testcase-alias/phandle-tests/consumer-a:testaliasoption".
^ ^ ^
0 14 39
The right length of alias 'testcase-alias' is 14, but the result worked
out by the API is 39 which is obvious wrong.
Fix by using index of either '/' or ':' as the length who comes earlier.
Fixes: 75c28c09af99 ("of: add optional options parameter to of_find_node_by_path()")
