#     slip: make slhc_free() silently accept an error pointer
#     
#     This way, slhc_free() accepts what slhc_init() returns, whether that is
#     an error or not.
#     
#     In particular, the pattern in sl_alloc_bufs() is
#     
#             slcomp = slhc_init(16, 16);
#             ...
#             slhc_free(slcomp);
#     
#     for the error handling path, and rather than complicate that code, just
#     make it ok to always free what was returned by the init function.
#     
#     That's what the code used to do before commit 4ab42d78e37a ("ppp, slip:
#     Validate VJ compression slot parameters completely") when slhc_init()
#     just returned NULL for the error case, with no actual indication of the
#     details of the error.
