lib/scatterlist.c: adjust indentation in __sg_alloc_table

BugLink: https://bugs.launchpad.net/bugs/1868627

[ Upstream commit 4e456fee ]

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.
