ext4: journal_path mount options should follow links

Browse Source 
Before the commit 461c3af045 ("ext4: Change handle_mount_opt() to use
fs_parameter") ext4 mount option journal_path did follow links in the
provided path.

Bring this behavior back by allowing to pass pathwalk flags to
fs_lookup_param().

Fixes: 461c3af045 ("ext4: Change handle_mount_opt() to use fs_parameter")
