Fix smatch warning for sg_nents_for_len return value in Inside Secure
EIP93 driver.
The return value of sg_nents_for_len was assigned to an u32 and the
error was ignored and converted to a positive integer.
Rework the code to correctly handle the error from sg_nents_for_len to
mute smatch warning.

Add support for the Inside Secure SafeXcel EIP-93 Crypto Engine used on
Mediatek MT7621 SoC and new Airoha SoC.
EIP-93 IP supports AES/DES/3DES ciphers in ECB/CBC and CTR modes as well as
authenc(HMAC(x), cipher(y)) using HMAC MD5, SHA1, SHA224 and SHA256.
EIP-93 provide regs to signal support for specific chipers and the
driver dynamically register only the supported one by the chip.
