Subject: [PATCH net-next v2 7/9] net/smc: Drop nr_pages_max initialization

splice_pipe_desc::nr_pages_max was initialized unnecessarily in
commit b8d199451c99 ("net/smc: Allow virtually contiguous sndbufs or RMBs
for SMC-R"). Struct's field is unused in this context.

Remove the assignment. No functional change intended.
