[PATCH] kasan: remove redundant initialization of variable 'real_size'

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Variable real_size is initialized with a value that is never read,
it is re-assigned a new value later on, hence the initialization is
redundant and can be removed.

Cleans up clang warning:
lib/test_kasan.c:422:21: warning: Value stored to 'real_size' during
its initialization is never read
