Documentation: net/smc: correct old value of smcr_max_recv_wr

The smc-sysctl.rst documentation incorrectly stated that
the previous hardcoded maximum number of WR buffers on
the receive path (smcr_max_recv_wr) was 16.
The correct historical value used before the introduction of
the sysctl control was 48. Update the documentation to reflect
the accurate historical value. Also fix a couple of minor typos.
