Wei Chen 92fbb6d129 i2c: xgene-slimpro: Fix out-of-bounds bug in xgene_slimpro_i2c_xfer() 
The data->block[0] variable comes from user and is a number between
0-255. Without proper check, the variable may be very large to cause
an out-of-bounds when performing memcpy in slimpro_i2c_blkwr.

Fix this bug by checking the value of writelen.
