Paul Moore 8251093971 selinux: improve error checking in sel_write_load()
[ Upstream commit 42c7732380 ]

Move our existing input sanity checking to the top of sel_write_load()
and add a check to ensure the buffer size is non-zero.

Move a local variable initialization from the declaration to before it
is used.

Minor style adjustments.
