On 32-bit environments, the sheepdog driver causes the following
compile warning because "%lx" is used for uint64_t type variables:
cc -c -DUSE_SIGNALFD -DUSE_TIMERFD -D_GNU_SOURCE -I. -g -O2
-fno-strict-aliasing -Wall -Wstrict-prototypes -fPIC
-DTGT_VERSION=\"\" -DBSDIR=\"/lib/tgt/backing-store\" bs_sheepdog.c -o
bs_sheepdog.o
bs_sheepdog.c: In function 'read_write_object':
bs_sheepdog.c:682: warning: format '%lx' expects type 'long unsigned
int', but argument 5 has type 'uint64_t'
bs_sheepdog.c:682: warning: format '%lx' expects type 'long unsigned
int', but argument 6 has type 'uint64_t'
This fixes the issue by using PRIx64 length modifier instead of "%lx".
