Aarch64: Remove dead qualifier initialisation

Removes an unused variable initialization in `encode_asimd_fcvt` function within the AArch64 assembler.

This patch removes an unused variable initialization in the encode_asimd_fcvt function in opcodes/aarch64-asm.c. The variable qualifier is initialized but its value is overwritten before it is used. Removing the dead initialization simplifies the code.

In Details

The patch removes the dead initialization of qualifier in opcodes/aarch64-asm.c::encode_asimd_fcvt. The variable is assigned AARCH64_OPND_QLF_NIL but is then always overwritten by a switch statement. Removing the initialization avoids a potentially misleading assignment.

For Context

binutils is a collection of binary tools such as the assembler, linker, etc. This patch modifies the assembler for the AArch64 architecture. The assembler translates human-readable assembly code into machine code that a computer can execute. The patch removes a variable initialization that's immediately overwritten, cleaning up the code.
