Fix up an error in iget removal in which romfs_lookup() making a successful
call to romfs_iget() continues through the negative/error handling (previously
the successful case jumped around the negative/error handling case):
(1) inode is initialised to NULL at the top of the function, eliminating the
need for specific negative-inode handling. This means the positive
success handling now flows straight through.
(2) Rename the labels to be clearer about what they mean.
Also make romfs_lookup()'s result variable of type long so as to avoid
32-bit/64-bit conversions with PTR_ERR() and friends.
Based upon a report and patch from Adam Richter.
