rtl8195am - fix i2c_api.c warnings 

Fix the following warnings:

[Warning] i2c_api.c@94,26: comparison between signed and unsigned integer expressions [-Wsign-compare]
[Warning] i2c_api.c@231,5: implicit declaration of function 'memset' [-Wimplicit-function-declaration]
[Warning] i2c_api.c@460,14: unused variable 'i2c_default_addr' [-Wunused-variable]
