[PATCH] misc: rtsx: Set setting_reg2 before use.

[Tom Rix <trix@redhat.com>]

The clang build fails with
rts5261.c:406:13: error: variable 'setting_reg2' is used uninitialized whenever 'if' condition is false [-Werror,-Wsometimes-uninitialized]
        } else if (efuse_valid == 0) {
                   ^~~~~~~~~~~~~~~~

setting_reg2 is set in this block
  if (efuse_valid == 2 || efuse_valid == 3) {
..
  } else if (efuse_valid == 0) {
    // default
..
  }
But efuse_valid can also have a value of 1.
Change the 'else if' to 'else' to make the second block the default.
