[PATCH 3.16 21/99] reiserfs: Fix spurious unlock in reiserfs_fill_super() error handling

[Ben Hutchings]

3.16.84-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Jan Kara <jack@xxxxxxx>

commit 4d5c1adaf893b8aa52525d2b81995e949bcb3239 upstream.

When we fail to allocate string for journal device name we jump to
'error' label which tries to unlock reiserfs write lock which is not
held. Jump to 'error_unlocked' instead.

Fixes: f32485be8397 ("reiserfs: delay reiserfs lock until journal initialization")
