fsdev: Fix overrun after readlink() fills buffer completely
readlink() returns the number of bytes written to the buffer, and it
doesn't write a terminating null byte.  do_readlink() writes it
itself.  Overruns the buffer when readlink() filled it completely.

Fix by reserving space for the null byte when calling readlink(), like
we do elsewhere.
