btrfs: don't stop searching after encountering the wrong item

commit 03b71c6ca6286625d8f1ed44aabab9b5bf5dac10 upstream.

The search ioctl skips items that are too large for a result buffer, but
inline items of a certain size occuring before any search result is
found would trigger an overflow and stop the search entirely.
