[PATCH] fs/befs/linuxvfs.c: need signed cast for variable 'block'

[Chen Gang <gang.chen@asianux.com>]

Need signed cast for it, the original author assume the type of 'block'
is long, so just cast to long. The related warnings (with allmodconfig):

  fs/befs/linuxvfs.c:136:2: warning: comparison of unsigned expression < 0 is always false [-Wtype-limits]
