[PATCH obv] Remove const in xtensa-linux-nat.c:fetch_gregs

[Simon Marchi <simon.marchi@ericsson.com>]

FYI, I pushed this as obvious.

Fixes:

/home/emaisin/src/binutils-gdb/gdb/xtensa-linux-nat.c: In function 'void fetch_gregs(regcache*, ptid_t, int)':
/home/emaisin/src/binutils-gdb/gdb/xtensa-linux-nat.c:178:23: error: uninitialized const 'regs' [-fpermissive]
   const gdb_gregset_t regs;
                       ^

gdb/ChangeLog:

	* xtensa-linux-nat.c (fetch_gregs): Remove const.
