media: hi556: Don't log hi556_check_hwcfg() errors twice

All hi556_check_hwcfg() error-exit paths already log a detailed reason,
logging a second generic "failed to check HW configuration" error is not
useful, and in case of the fwnode check failing with -EPROBE_DEFER this
is outright problematic flooding the log with:

[    6.336318] hi556 i2c-INT3537:00: failed to check HW configuration: -517
[    6.339006] hi556 i2c-INT3537:00: failed to check HW configuration: -517
[    6.346293] hi556 i2c-INT3537:00: failed to check HW configuration: -517
[    6.356129] hi556 i2c-INT3537:00: failed to check HW configuration: -517
[    6.380316] hi556 i2c-INT3537:00: failed to check HW configuration: -517
etc.

The one exception to all hi556_check_hwcfg() error-exit paths already
logging an error is on v4l2_fwnode_endpoint_alloc_parse() errors.

Make hi556_check_hwcfg() log an error in that case too and drop
the duplicate "failed to check HW configuration" error logging.
