NFSv4.2: Fix READ_PLUS smatch warnings
Smatch reports:
fs/nfs/nfs42xdr.c:1131 decode_read_plus() warn: missing error code? 'status'
Which Dan suggests to fix by doing a hardcoded "return 0" from the
"if (segments == 0)" check.
Additionally, smatch reports that the "status = -EIO" assignment is not
used. This patch addresses both these issues.
