serial: sh-sci: fix memory region release in error path
The sci_request_port() function uses request_mem_region() to reserve
I/O memory, but in the error path when sci_remap_port() fails, it
incorrectly calls release_resource() instead of release_mem_region().
This mismatch can cause resource accounting issues. Fix it by using
the correct release function, consistent with sci_release_port().
Fixes: e2651647080930a1 ("serial: sh-sci: Handle port memory region reservations.")
