[PATCH][next] net: ipa: remove the redundant assignment to variable trans_id

[Colin Ian King <colin.i.king@gmail.com>]

The variable trans_id is being modulo'd by channel->tre_count and
the value is being re-assigned back to trans_id even though the
variable is not used after this operation. The assignment is
redundant. Remove the assignment and just replace it with the modulo
operator.

Cleans up clang scan build warning:
warning: Although the value stored to 'trans_id' is used in the
enclosing expression, the value is never actually read from
'trans_id' [deadcode.DeadStores]
