cxl/pci: fix error code in __cxl_hdm_decode_init()

When commit 0cab68720598 ("cxl/pci: Fix disabling memory if DVSEC CXL
Range does not match a CFMWS window") was backported, this chunk moved
from the cxl_hdm_decode_init() function which returns negative error
codes to the __cxl_hdm_decode_init() function which returns false on
error.  So the error code needs to be modified from -ENXIO to false.

This issue only exits in the 6.1.y kernels.  In later kernels negative
error codes are correct and the driver didn't exist in earlier kernels.
