cleanup: remove count_divecomputers() function

Browse source 
There is a number_of_computers() function which does
the same thing with two exceptions:
1) checks for null-dive
2) returns an unsigned int

Replace calls to count_divecomputers() by calls to number_of_computers().
In one case, the return type makes a different - add a cast to int there.
Ultimately, we should probably change the dc_number to signed int
throughout the code.
