media: rzg2l-cru: fix a test for timeout
The test for if the loop timed out is wrong and Smatch complains:
drivers/media/platform/renesas/rzg2l-cru/rzg2l-csi2.c:411 rzg2l_csi2_mipi_link_disable()
warn: should this be 'timeout == -1'
Let's change it to a preop loop instead of a post op loop.
Fixes: 51e8415e39a9 ("media: platform: Add Renesas RZ/G2L MIPI CSI-2 receiver driver")
