soc: mediatek: pwrap: Zero initialize rdata in pwrap_init_cipher
[ Upstream commit 89e28da82836530f1ac7a3a32fecc31f22d79b3e ]
When building with -Wsometimes-uninitialized, Clang warns:
drivers/soc/mediatek/mtk-pmic-wrap.c:1358:6: error: variable 'rdata' is
used uninitialized whenever '||' condition is true
[-Werror,-Wsometimes-uninitialized]
If pwrap_write returns non-zero, pwrap_read will not be called to
initialize rdata, meaning that we will use some random uninitialized
stack value in our print statement. Zero initialize rdata in case this
happens.
