[PATCH v2] xfs_repair: Add missing braces

[Xiao Yang <yangx.jy@cn.fujitsu.com>]

When xlog_find_tail() fails to find the head or the tail, the missing
braces leads that an unparseable log always exits with status 2, even
if we've asked for -n or -L which should proceed.  We can expose this
issue by xfstests case xfs/098.

Fixes:'commit b04647edea32 ("xfs_repair: exit with status 2 if log dirtiness is unknown")'
