cxl/mbox: Remove useless cast in cxl_mem_create_range_info()

DEFINE_RES_MEM() is a wrapper around the DEFINE_RES_NAMED() macro
which already has the (struct resource) for the compound literal.
The user of the macro should not repeat the cast.

Cleans up these sparse warnings:
drivers/cxl/core/mbox.c:1184:18: warning: cast to non-scalar
drivers/cxl/core/mbox.c:1184:18: warning: cast from non-scalar

Fixes: 52c4d11f1dce ("resource: Convert DEFINE_RES_NAMED() to be compound literal")
