    Fix unused variable warning in if_pfsync.c
    
    With clang 15, the following -Werror warning is produced:
    
        sys/netpfil/pf/if_pfsync.c:2153:9: error: variable 'sent' set but not used [-Werror,-Wunused-but-set-variable]
                int i, sent = 0;
                       ^
    
    The 'sent' variable was used in the for loop later in the
    pfsync_bulk_update() function, but refactoring in 4fc65bcbe3fb7 got rid
    of it. Remove the variable since it no longer serves any purpose.
    
    MFC after:      3 days
    
    (cherry picked from commit fb48e998501f8d1defecffb772121a4141cdc2b6)
