drm/bridge: analogix_dp: Extract error pointer from correct variable

In devm_drm_panel_bridge_add() error path the pointer error should be
extracted from dp->plat_data->next_bridge but instead it is extracted
from bridge, which is a valid pointer and not part of this error path.

Extract error pointer from correct variable.

Detected by Smatch:
drivers/gpu/drm/bridge/analogix/analogix_dp_core.c:1489 analogix_dp_bind()
warn: passing a valid pointer to 'PTR_ERR'
