i2c: rtl9300: Fix out-of-bounds bug in rtl9300_i2c_smbus_xfer
The data->block[0] variable comes from user. Without proper check,
the variable may be very large to cause an out-of-bounds bug.
Fix this bug by checking the value of data->block[0] first.
1. commit 39244cc75482 ("i2c: ismt: Fix an out-of-bounds bug in
ismt_access()")
2. commit 92fbb6d1296f ("i2c: xgene-slimpro: Fix out-of-bounds bug in
xgene_slimpro_i2c_xfer()")
Fixes: c366be720235 ("i2c: Add driver for the RTL9300 I2C controller")
