[PATCH] video: fbdev: uvesafb: Fixes an error handling path in 'uvesafb_probe()'

If an error occurs after a successful 'uvesafb_init_mtrr()' call, it must
be undone by a corresponding 'arch_phys_wc_del()' call, as already done in
the remove function.

This has been added in the remove function in commit 63e28a7a5ffc
("uvesafb: Clean up MTRR code")

Fixes: 8bdb3a2d7df4 ("uvesafb: the driver core")
