[PATCH] hostfs: fix 32-bit crash

[Johannes Berg]

From: Johannes Berg <johannes.berg at intel.com>

dev_t is a kernel type and may have different definitions
in kernel and userspace. On 32-bit x86 this currently makes
the stat structure being 4 bytes longer in the user code,
causing stack corruption. Just use 'unsigned int' so the
same size is used.
