Subject: [PATCH] lib/scatterlist: Adjust indentation in __sg_alloc_table

Clang warns:

../lib/scatterlist.c:314:5: warning: misleading indentation; statement
is not part of the previous 'if' [-Wmisleading-indentation]
                        return -ENOMEM;
                        ^
../lib/scatterlist.c:311:4: note: previous statement is here
                        if (prv)
                        ^
1 warning generated.

This warning occurs because there is a space before the tab on this
line. Remove it so that the indentation is consistent with the Linux
kernel coding style and clang no longer warns.

This file doesn't seemt to have a formal maintainer but Jens seems to
have a few signoffs. If not, I assume Andrew will take it.
