net: openthread: Print the actual assert location

When OpenThread application is built with CONFIG_ASSERT
and CONFIG_ASSERT_NO_MSG_INFO, OT_ASSERT() prints a location
that points to the otPlatAssertFail() function instead of
the code that actually failed an assertion.

This is confusing and CONFIG_ASSERT_NO_MSG_INFO sometimes
cannot be disabled because of flash size limitations.

Make otPlatAssertFail() always print the actual assert
location.
