CIFS: cleanup min_t() cast in cifs_read()
Smatch complains that the cast to "int" in min_t() changes very large values of current_read_size into negative values and so min_t() could return the wrong value. I removed the const as well, as that doesn't do anything here. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Steve French <smfrench@gmail.com>
