[PATCH 5/5] watchdog: dw_wdt: clean up error paths in resume function

[Artem Shimko <a.shimko.dev@gmail.com>]

Clean up of dw_wdt_resume() function.

Rework the error handling to use properly named labels that match the
cleanup order. Use unprepare_clk for clock disable and unprepare_pclk
for pclk disable path.
