cluster/ec: Fix issues with eager locking

Due to a race in timer cancellation, in some cases it was possible
to unlock the lock while another concurrent fop that needed it
continues execution as if it were not released.

This patch also fixes an issue that caused a lock to not be released
if an error was found while preparing ec_update_size_version().
