Memory was not released (as it would be expected) when one call
of further resource reservations failed.

This was the only thing in this series that triggered more than a,
very uninspired, "meh" on first read.

Will it matter here if the function "kfree" will be called for the
data structure members "bcs" and "inbuf" after a later function call
failed within the implementation of "gigaset_initcs"?
