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.
Fixes: b1c5f3085149 ("misc: rtsx: add rts5261 efuse function")
