btrfs-progs: consitfy keys passed to serch functions
When using gcc8 to compile btrfs-progs, it complains as below:
ctree.c: In function 'btrfs_search_slot_for_read':
ctree.c:1249:45: warning: passing argument 3 of 'btrfs_search_slot'
discards 'const' qualifier from pointer target type
[-Wdiscarded-qualifiers]
ret = btrfs_search_slot(NULL, root, key, p, 0, 0);
Change btrfs_search_slot prototype with 'const' qualifier for argument 3.
Also fix similar problems as above change.
