cifs: fix artificial limit on reading symlinks
There's no reason to limit the size of a symlink that we can read to 4000 bytes. That may be nowhere near PATH_MAX if the server is sending UCS2 strings. CIFS should be able to read in a symlink up to the size of the buffer. The size of the header has already been accounted for when creating the slabcache, so CIFSMaxBufSize should be the correct size to pass in. Fixes samba bug #6384.
