Qu Wenruo cb19235991 btrfs-progs: tests: misc/046: fix false alerts on write detection
[BUG]
Test case misc/046-seed-multi-mount would always fail with the following
error:

    [TEST]   misc-tests.sh
    [TEST/misc]   046-seed-multi-mount
unexpected success: writable file despite read-only mount
test failed for case 046-seed-multi-mount

[CAUSE]
Although mounting seed device is indeed read-only, sprouting it with a
new device would always make it read-write by itself.

The behavior is already there for a long time, thus expecting a new
behavior (not changing the read-only flag) is a little weird.

[FIX]
Instead of doing the write check after the sprout, do it before the
sprout.

This looks more correct, and would not rely on the kernel behavior
change (if we determine to go that path).
