[PATCH AUTOSEL 4.9 057/141] reiserfs: Fix spurious unlock in reiserfs_fill_super() error handling

[Sasha Levin]

From: Jan Kara <jack@xxxxxxx>

[ Upstream commit 4d5c1adaf893b8aa52525d2b81995e949bcb3239 ]

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")
