net: stmmac: dwmac-anarion: Always return struct anarion_gmac * from anarion_config_dt()
Always return struct anarion_gmac * from anarion_config_dt().
In the case where ctl_block was an error pointer it was being
returned directly. Which sparse flags as follows:
.../dwmac-anarion.c:73:24: warning: incorrect type in return expression (different address spaces)
.../dwmac-anarion.c:73:24: expected struct anarion_gmac *
.../dwmac-anarion.c:73:24: got void [noderef] __iomem *[assigned] ctl_block
Avoid this by converting the error pointer to an error.
And then reversing the conversion.
As a side effect, the error can be used for logging purposes,
subjectively, leading to a minor cleanup.
No functional change intended.
Compile tested only.
