Nathan Chancellor bd476c1306 misc: rtsx: Fix clang -Wsometimes-uninitialized in rts5261_init_from_hw() 
Clang warns:

  drivers/misc/cardreader/rts5261.c:406:13: error: variable 'setting_reg2' is used uninitialized whenever 'if' condition is false [-Werror,-Wsometimes-uninitialized]
          } else if (efuse_valid == 0) {
                     ^~~~~~~~~~~~~~~~
  drivers/misc/cardreader/rts5261.c:412:30: note: uninitialized use occurs here
          pci_read_config_dword(pdev, setting_reg2, &lval2);
                                      ^~~~~~~~~~~~

efuse_valid == 1 is not a valid value so just return early from the
function to avoid using setting_reg2 uninitialized.
