Subject: [PATCH i2c-host-fixes i2c-host v7 1/2] i2c: rtl9300: Drop
 unsupported I2C_FUNC_SMBUS_BLOCK_DATA

While applying the patch for commit ede965fd555a ("i2c: rtl9300: remove
broken SMBus Quick operation support"), a conflict was incorrectly solved
by adding the I2C_FUNC_SMBUS_I2C_BLOCK feature flag. But the code to handle
I2C_SMBUS_I2C_BLOCK_DATA requests will be added by a separate commit.

Fixes: ede965fd555a ("i2c: rtl9300: remove broken SMBus Quick operation support")
Cc: stable@...r.kernel.org # v6.13+
