USB: sierra: fix urb and memory leak in resume error path

Neither the transfer buffer or the urb itself were released in the
resume error path for delayed writes. Also on errors, the remainder of
the queue was not even processed, which leads to further urb and buffer
leaks.

The same error path also failed to balance the outstanding-urb counter,
something which results in degraded throughput or completely blocked
writes.

Fix this by releasing urb and buffer and balancing counters on errors,
and by always processing the whole queue even when submission of one urb
fails.
