ubifs: Fix uninitialized use of err in ubifs_jnl_write_inode()

Clang warns (or errors with CONFIG_WERROR=y):

  fs/ubifs/journal.c:986:20: error: variable 'err' is uninitialized when used here [-Werror,-Wuninitialized]
    986 |                 ubifs_ro_mode(c, err);
        |                                  ^~~

Set err to -EPERM before the call to ubifs_ro_mode() and reuse it in the
return statement to resolve the warning.
