auxdisplay: arm-charlcd: fix release_mem_region() size
[ Upstream commit b5c23a4d291d2ac1dfdd574a68a3a68c8da3069e ]
It seems like, after the request_mem_region(), the corresponding
release_mem_region() must take the same size. This was done
in (now removed due to previous refactoring) charlcd_remove()
but not in the error path in charlcd_probe().
Fixes: ce8962455e90 ("ARM: 6214/2: driver for the character LCD found in ARM refdesigns")
