qcacmn: Check for equal case in nbuf len sanity
MSDU with len 1654 is received in the REO2SW ring and
the total len of the pkt would be 1654 + 392 (pkt tlvs)
+ 2 (l2 hdr padding) = 2048bytes. The nbuf len sanity
checks for strictly less than 2048 bytes which results
in the assertion failure.
Fix is to add the equal case when validating the
nbuf len.
