hwrng: amd - Convert PCIBIOS_* return codes to errnos
commit 14cba6ace79627a57fb9058582b03f0ed3832390 upstream.
amd_rng_mod_init() uses pci_read_config_dword() that returns PCIBIOS_*
codes. The return code is then returned as is but amd_rng_mod_init() is
a module_init() function that should return normal errnos.
Convert PCIBIOS_* returns code using pcibios_err_to_errno() into normal
errno before returning it.
Fixes: 96d63c0297cc ("[PATCH] Add AMD HW RNG driver")
