rsi: Properly initialize data in rsi_sdio_ta_reset
When building with -Wuninitialized, Clang warns:
drivers/net/wireless/rsi/rsi_91x_sdio.c:940:43: warning: variable 'data'
is uninitialized when used here [-Wuninitialized]
put_unaligned_le32(TA_HOLD_THREAD_VALUE, data);
^~~~
drivers/net/wireless/rsi/rsi_91x_sdio.c:930:10: note: initialize the
variable 'data' to silence this warning
u8 *data;
^
= NULL
1 warning generated.
Using Clang's suggestion of initializing data to NULL wouldn't work out
because data will be dereferenced by put_unaligned_le32. Use kzalloc to
properly initialize data, which matches a couple of other places in this
driver.
