NFSv4.1: cleanup filelayout invalid deviceid handling
Move the invalid deviceid test into nfs4_fl_prepare_ds, called by the
filelayout read, write, and commit routines. NFS4_DEVICE_ID_NEG_ENTRY
is no longer needed.
Remove redundant printk's - filelayout_mark_devid_invalid prints a KERN_WARNING.
An invalid device prevents pNFS io.
