mm/iob/Kconfig: Make the default of IOB_NCHAINS same as IOB_NBUFFERS. It is reasonable default value since iob_qentry_s is much small than iob_s and could avoid the buffer can be allocated but the chain can't: 'tcp_datahandler: ERROR: Failed to queue the I/O buffer chain: -12'

These tiny nodes are used as "containers" to support queueing of
I/O buffer chains. This will limit the number of I/O transactions
