cifs: extend the buffer length enought for sprintf() using
commit 057d6332b24a4497c55a761c83c823eed9e3f23b upstream.
For cifs_set_cifscreds() in "fs/cifs/connect.c", 'desc' buffer length
is 'CIFSCREDS_DESC_SIZE' (56 is less than 256), and 'ses->domainName'
length may be "255 + '\0'".
The related sprintf() may cause memory overflow, so need extend related
buffer enough to hold all things.
It is also necessary to be sure of 'ses->domainName' must be less than
256, and define the related macro instead of hard code number '256'.
