usb: bdc: Fix an error handling path in 'bdc_probe()' when no suitable DMA config is available 

[ Upstream commit d2f42e09393c774ab79088d8e3afcc62b3328fc9 ]

If no suitable DMA configuration is available, a previous 'bdc_phy_init()'
call must be undone by a corresponding 'bdc_phy_exit()' call.

Branch to the existing error handling path instead of returning
directly.
