Reset initing when init fails to avoid permanent skip

If remoteEntryExports.init(...) or the hooks throw, initing remains true and inited stays false, so subsequent init() calls will skip initialization forever and still return remoteEntryExports, leaving the remote uninitialized. This only happens after a transient failure (network error, bad remote entry, hook exception), but in that case it permanently blocks recovery in the same process. Consider resetting initing in a finally/catch so a later retry can re-run initialization.
