[PATCH] libfuse option parsing

[Thiébaud Weksteen]

Hi @tech,

Two fixes for libfuse and option parsing. According to the official 
implementation, when an option is not recognised, the processing function
should be called with the key FUSE_OPT_KEY_OPT [1]. Additionally, fix the
last argument of a call in fuse_opt_parse.

Thanks,
Thiébaud
