bookmarks: check @pathalias suffix before available @number for efficiency

Before this patch, available "@number" suffix is searched before
"@pathalias" suffix, even though the latter has higher priority than
the former if the latter exits.

This patch checks "@pathalias" suffix before available "@number" for
efficiency.

When an URL has multiple path definitions, the first one is used for
"pathalias" after this patch, even though the last one is used before
this patch, because:

  - this choice can terminate loop immediately for efficiency
  - such case seems to be rare
