nfs: fix nfs4d readlink truncated packet
XDR requires 4-byte alignment; nfs4d READLINK reply writes out the padding,
but truncates the packet to the padding-less size.
Fix by taking the padding into consideration when truncating the packet.
Symptoms:
# ll /mnt/
ls: cannot read symbolic link /mnt/test: Input/output error
