Commit 7d968b5badfc ("media: hi556: Return -EPROBE_DEFER if no endpoint is
found") moved the v4l2_fwnode_endpoint_alloc_parse() call in
hi556_check_hwcfg() up, but it did not make the error-exit paths between
the old and new call-site use "goto check_hwcfg_error;" to free the bus_cfg
on errors.
Add the missing "goto check_hwcfg_error;" statements to fix a memleak on
early error-exits from hi556_check_hwcfg().
Fixes: 7d968b5badfc ("media: hi556: Return -EPROBE_DEFER if no endpoint is found")
