[PATCH 2/2] alfred: free the correct capability set when cap_init() fails

[Sven Eckelmann <sven@narfation.org>]

reduce_capabilities() first allocates the current capability state with
cap_get_proc() into cap_cur and then allocates a fresh capability set
with cap_init() into cap_new. When the latter fails it tries to deallocate
the NULL cap_new.

Free cap_cur instead to avoid a leak.
