Horia Geanta b62ffd8c72 crypto: talitos - fix locating offending descriptor in error path
Commit 3e721aeb3d
("crypto: talitos - handle descriptor not found in error path")
tried to address the fact that CDPR (Current Descriptor Pointer Register)
is unreliable.

As it turns out, there are still issues in the function detecting the
offending descriptor:
-only 32 bits of the descriptor address are read, however the address is
36-bit - since reset_channel() initializes channels with EAE (extended
address) bit set
-reading CDPR can return zero in cur_desc; when searching the channel
fifo for this address, cur_desc == dma_desc (= 0) case might happen,
leading to an oops when trying to return desc->hdr (desc is zero)
-read channel's .tail only once; the tail is a moving target; use a
local variable for the end of search condition
