misc: mic: scif: scif_api: Remove set but unused variable 'read_size'
'read_size' appears to have been assigned, but never used since the
SCIF messaging and node enumeration APIs were introduced in 2015.
Makes sense to simply remove it.
Fixes the following W=1 warning:
drivers/misc/mic/scif/scif_api.c: In function ‘_scif_recv’:
drivers/misc/mic/scif/scif_api.c:1000:6: warning: variable ‘read_size’ set but not used [-Wunused-but-set-variable]
1000 | int read_size;
