Dmitry Monakhov 365b680fe4 tcm_fileio: Prevent information leak for short reads 
[ Upstream commit f11b55d13563e9428c88c873f4f03a6bef11ec0a ]

If we failed to read data from backing file (probably because some one
truncate file under us), we must zerofill cmd's data, otherwise it will
be returned as is. Most likely cmd's data are unitialized pages from
page cache. This result in information leak.

(Change BUG_ON into -EINVAL se_cmd failure - nab)
