When multiple tfm use a same qp, the backlog data should be managed
centrally by the qp, rather than in the qp_ctx of each req.
Additionally, since SEC_BD_TYPE1 and SEC_BD_TYPE2 cannot use the
tag of the sqe to carry the virtual address of the req, the sent
sqe is stored in the qp. This allows the callback function to get
the req address. To handle the differences between hardware types,
the callback functions are split into two separate implementations.

The fips_enable() function is only invoked early during kernel boot via the
__setup() macro ("fips=" command line parameter), and is never used again
after initialization completes.
Annotating it with __init places the function in the .init.text section,
allowing the kernel to free its memory after init (when freeing_initmem()
runs), reducing runtime memory footprint.
This is a standard practice for setup/early-parse functions and has no
functional impact — the parsing logic, return values, and fips mode
setting behavior remain unchanged.

'strlen(buf) > 64' to check the length, but then strscpy() copies only
63 characters before adding a NUL terminator, silently truncating the
