smb: client: fix possible double free in smb2setea()
Clang static checker(scan-build) warning： fs/smb/client/smb2ops.c:1304:2: Attempt to free released memory. 1304 | kfree(ea); | ^~~~~~~~~
There is a double free in such case: 'ea is initialized to NULL' -> 'first successful memory allocation for ea' -> 'something failed, goto seaexit' -> 'first memory release for ea' -> 'goto replayagain' -> 'second goto sea_exit before allocate memory for ea' -> 'second memory release for ea resulted in double free'.
Re-initialie 'ea' to NULL near to the replay_again label, it can fix this double free problem.
