drivers: block: correct brackets

GCC complained on linux-next about

drivers/block/loop.c:1149:3: warning: this ‘if’ clause does not guard... [-Wmisleading-indentation]
if (figure_loop_size(lo, info->lo_offset, info->lo_sizelimit, ^~
drivers/block/loop.c:1152:4: note: ...this statement, but the latter is misleadingly indented as if it is guarded by the ‘if’

    goto exit;

This adjustes the brackets to the inner if.
