H A Dnfs4layouts.cdiff 6f8f28ec5f88715515e70dd52f16b326a5e63f81 Thu Mar 19 12:04:14 CET 2015 Kinglong Mee <kinglongmee@gmail.com> NFSD: Check layout type when returning client layouts

According to RFC5661:
" When lr_returntype is LAYOUTRETURN4_FSID, the current filehandle is used
to identify the file system and all layouts matching the client ID,
the fsid of the file system, lora_layout_type, and lora_iomode are
returned. When lr_returntype is LAYOUTRETURN4_ALL, all layouts
matching the client ID, lora_layout_type, and lora_iomode are
returned and the current filehandle is not used. "

When returning client layouts, always check layout type.
