nfsd: add a nfserrno mapping for -E2BIG to nfserr_fbig
I saw this pop up with some pynfs testing: [ 123.609992] nfsd: non-standard errno: -7 ...and -7 is -E2BIG. I think what happened is that XFS returned -E2BIG due to some xattr operations with the ACL10 pynfs TEST (I guess it has limited xattr size?). Add a better mapping for that error since it's possible that we'll need it. How about we convert it to NFSERR_FBIG? As Bruce points out, they both have "BIG" in the name so it must be good. Also, turn the printk in this function into a WARN() so that we can get a bit more information about situations that don't have proper mappings.
