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.
