afr: fix log flooding
Commit "ccf33e789 - dict.c: remove redundant checks"
removed some NULL checks in certain dict functions. This caused
flooding of fuse mount logs when I/O was done on the mount on a replica
volume:
Message:
W [dict.c:1478:dict_get_with_refn]
(-->/usr/local/lib/libglusterfs.so.0(dict_get_uint32+0x4d)
[0x7ff9121ec963] -->/usr/local/lib/libglusterfs.so.0(dict_get_with_ref+0x90)
[0x7ff9121eb93f] -->/usr/local/lib/libglusterfs.so.0(+0x229be)
[0x7ff9121eb9be] ) 0-dict: dict OR key (glusterfs.lk.lkmode) is NULL [Invalid argument]
Fix:
In the relevant AFR functions, check that dict is not NULL before trying
to perform operations on it.
See bug description for more details.
