[PATCH v3 1/1] i2c: core: replace boolean variable by integer

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

There is a warning when compiling i2c-core.c
drivers/i2c/i2c-core.c:2561:36: warning: dubious: x | !y

Replace boolean exdpression by a plain bitwise AND since I2C_M_RD is a bit 0
and thus we are on the safe side.
