ice: fix numeric overflow warning
When compiling and analyzing the driver on newer kernels, a static
analyzer warns about the following "numeric overflow" issues:
"The result of expression: 'budget-1' generates 4-byte type while casting
to a bigger size of 8-byte".
"The result of expression: '*words-words_read' generates 4-byte type
while casting to a bigger size of 8-byte".
Fix them both.
