[patch 7/7] Fix misleading gcc4 warning: (160) offset and block may be used uninitialized in this function

This warning appears to be a false alarm.

This patch eliminates the warning that 'offset' and 'block' may be used
uninitialized. The compiler does not like the conditional initialization
of the two variables in the function isofs_find_entry().

In isofs_find_entry(), 'offset' and 'block' are referred to as
'block_rv' and 'offset_rv' respectively and are now initialized
unconditionally to zero.
