[PATCH] mm: fix some compile errors on x86 arch

[Wei Yongjun <yjwei@cn.fujitsu.com>]

This patch fixed the following compile errors on x86 arch:

p2m.c: In function ‘p2m_change_type_global’:
p2m.c:2211: error: ‘i4’ undeclared (first use in this function)

mem_sharing.c: In function ‘mem_sharing_hash_delete’:
mem_sharing.c:217: error: format ‘%lx’ expects type ‘long unsigned int’,
but argument 2 has type ‘shr_handle_t’
