[PATCH] staging: most: dim2: fix missing cleanup on interface registration failure

[Navaneeth K <knavaneeth786@gmail.com>]

If most_register_interface() fails, the function returned immediately
without freeing the allocated 'dev' structure or resetting the hardware
state via dim_shutdown().

Add a proper error path that jumps to the existing error handling label
to ensure resources are freed and the hardware is shut down correctly.
