selftests/mm: fix compiler -Wmaybe-uninitialized warning
Following build warning comes up for cow test as 'transferred' variable has
not been initialized. Fix the warning via zero init for the variable.
CC cow
cow.c: In function `do_test_vmsplice_in_parent':
cow.c:365:61: warning: `transferred' may be used uninitialized [-Wmaybe-uninitialized]

| ~~~~~~~~~~~~^~~~~~~
cow.c:296:29: note: `transferred' was declared here
