dax: Fix alloc_dax_region() compile warning
[ Upstream commit 460370ab20
]
PFN flags are (unsigned long long), fix the alloc_dax_region() calling
convention to fix warnings of the form:
>> include/linux/pfn_t.h:18:17: warning: large integer implicitly truncated to unsigned type [-Woverflow]
#define PFN_DEV (1ULL << (BITS_PER_LONG_LONG - 3))
