i2c: rtl9300: fix channel number bound check
Fix the current check for number of channels (child nodes in the device
tree). Before, this was:
if (device_get_child_node_count(dev) >= RTL9300_I2C_MUX_NCHAN)
RTL9300_I2C_MUX_NCHAN gives the maximum number of channels so checking
with '>=' isn't correct because it doesn't allow the last channel
number. Thus, fix it to:
if (device_get_child_node_count(dev) > RTL9300_I2C_MUX_NCHAN)
Issue occured on a TP-Link TL-ST1008F v2.0 device (8 SFP+ ports) and fix
is tested there.
