media: Staging: media: Release the correct resource in an error handling path

Browse source

'res' is reassigned several times in the function and if we 'goto
error_unmap', its value is not the returned value of 'request_mem_region()'
anymore.

Introduce a new 'struct resource *' variable (i.e. res2) to keep a pointer
to the right resource, if needed in the error handling path.

Fixes: 4b4eda0017 ("Staging: media: Unmap and release region obtained by ioremap_nocache")
