fbdev: uvesafb: Fixes an error handling path in uvesafb_probe()
[ Upstream commit a94371040712031ba129c7e9d8ff04a06a2f8207 ]
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")
